Totally doable. You can buy Iodine tabs, first aid kits and accessories (piece it together yourself), Magnesium bar, Waterproof pelican style cases, match containers, spectra line (cheapest spot to buy it actually), snare wire (hardware department labeled brass wire 22-24 gauge I think), hooks, sinkers, duct tape, whistle (low quality though, and I would recommend a Fox 40 instead of Walmart brand), mylar blanket, and almost everything you'd need (almost).
Not a bad spot to find a LOT of inexpensive equipment. Some things like the whistle I recommend NOT skimping on though. You must give us the rundown when you come through and back it up with pictures.
