I did exactly what you are proposing....except I started with just $3000.
I had done a "market survey" in an indoor flea market for the summer and fall. There definately seemed to be a market. So I opened up a knife store in a mall for the Christmas season of 2000...opened it Oct. 1st when the rent was still lower than Nov. and Dec. tend to be. I had a 600 sq ft store front that had been a Candy Castle. It was the smallest store in the mall, and had a castle themed front that I drew on in ordering supplies. I begged and borrowed all of the display cases. (I moved them around so they took up the most space so as to not look so sparse.) I paid the first month's rent and security deposit. I then spent the rest of that $3000 for supplies...a mix of cheap swords, fantasy knives, and a cheaper line of main-stream production knives (mostly CRKT and imports). I was fortunate enough to qualify for a couple of 30 day net on gift items like dragons, fairies, unicorns, etc.
The Christmas season was amazing! Extreme hours (store hours of 7am to 11pm during the Christmas rush)...the need to hire a friend part-time, then full time...but also a suprising amount of cash-flowing into the store. After all the bills were paid, I netted $14K for those 3 months! The mall was very pleased with the store (I had been able to add a number of extra cases during those 3 months so it looked very nice), and asked me to stay.
The months after Christmas were obviously not as good, and I struggled a bit, but not as much as I'd feared. I was still netting a profit each month. I also added a few other employees so I could have a "normal" work schedule. (During that first Christmas season I was at the store from an hour before opening to an hour after closing seven days a week.)
I added better production knives as I was able, and the store, and the clientel upgraded rather nicely. I found this site while I was still doing viable market research which greatly added to my knowledge. I attended the Show Show in 2001 and found more suppliers. Because the store was still small, I opted to stay with distributors in most cases rather than dealing straight with manufacturers.
After talking to a number of other store owners during SHOT and the Blade Show, I decided to expand to another store using the same forumla I had used before (open early in the Christmas season). I talked to a number of malls, and had decided on one just over an hour north that was very close to where my friend/employee lived (who would then become the manager for that store). I was to sign the lease on Sept. 13th of 2001. Obviously we all know what happened 2 days before I was to sign the lease....I got a call on Sept 12th from the mall telling me that "because of the current situation, and the feelings toward weapons, they felt that a store such as mine would not be the type of message the mall wished to convey."
At this point I made a grave tactal error and went with my second choice....a mall almost 2 hours south of my established store...an area in which I knew no one, and had to find a manager that I didn't know. I dipped into my savings to buy display cases for both stores, and supply the second store since it was much bigger than my current store, or first choice for expansion. It turned out to be a bad decision in that I had not realized the economic down-turn that resulted from 9-11. I also could not get down as often as I wanted to, and had to rely on strangers to run the store. (I allowed some hiring mistakes because of it.)
The new store did just ok that Christmas. Unfortunately instead of signing a lease just though the Christmas season, I had had to sign a years lease up-front.
I managed to keep the second store open until June, but had to renegotiate my lease and take a major loss to get out. I hoped the orignial store would make up for some of that loss over the Christmas season. That Christmas season wasn't quite as good as the one before, but I survived.
I managed to scrape by (by dipping into my life-savings) all that Spring and Summer, educating my established customer base, and switching to better (and more expensive) major band knives. Unfortunately that was not especially condusive to attracting new customers, but I had turned into a major knife snob. I refused to buy imported knives from manufacturers known to knock-off major-brand knives. During this time the internet glut of knives marked up bare percentages started in full-force. Shipping was still quite cheap. I had plenty of "customers" that would love to come in and see all the newest knives, then go home to their computers to order from someone cheaper.
After that Christmas (which had again been somewhat down from that first year), the mall decided I must become a permanent store which would almost triple my rent! After a lot of soul searching and number crunching, I decided that I just couldn't afford to stay in the mall. (I tried to make a go of it in a small storefront about 6 miles away that just didn't work out....losing too much of my life-savings, in a desperate attempt to make it work.) I am now working for someone else, slowly climbing the ladder toward middle management, and trying to make up for that lost retirement savings.
Sorry that was so long, but it is an honest attempt to let you know both the good and bad that can happen. I learned a lot, had my plans changed by situations out of my control, made many mistakes, some of which turned out to be major mistakes, and had a blast and for a while made some decent money and lived out a wonderful dream.
The best advice I can give you is to do serious market analysises (the indoor flea market worked well for me), constantly think though your goals and objectives, to be able to roll with the punches that life deals you. A business plan updated yearly is a great idea. Perhaps just open a seasonal store for Christmas in a mall for a couple of years. Retail in general starves from January to late Oct of every year. (If you decide on a seaonal store, opening in Oct is a good idea to give potential customers ideas before the rush.)
If you have any questions, email me and I'll be glad to help as much as possible.
