Check out Atlas Knife and Tools. Charles is a member here and makes very affordable forges and anvils.
If you want to spend more on a forge, I highly recommend the NC Too and Forge company Whisper forges. The
Lowboy is very versatile. The
Knifemaker is great if you will only do knives.
Kayne and Sons (Blacksmith Depot) is a great source for tongs and hammers.
If you use the custom search engine in the stickys you will find a lot of treads on your questions:
Here is some past advice I gave on this question:
I recommend that you start with a few basic tongs and a hammer or two. Once you get started, you will find what you need and get those items. I have over forty hammers and buckets of tongs....but use two hammers and three tongs for 99% of all forging.
For about $150 I would get:
Tongs - bladesmiths don't need huge long tongs. All we need to do is hold hot stuff while hammering it. Use the shortest tongs that will do the job. I highly recommend Blacksmith's Depot tongs and hammers:
One pair of simple short "pick up" tongs for doing HT and putting things in and out of the forge. I recommend the "half-round 300mm tongs

One pair of general use blade forging tongs, like the 1" blade tongs.

One pair of offset tongs with general use jaws, like the Gooseneck "V" bit tongs.

Hammers can come in many shapes and sizes. To start with get a very basic hammer and learn to forge. Specialty hammers will come to you as you need them. Going to HF and getting a basic blacksmiths cross peen hammer isn't a bad starter. If you want a real, smiths hammer, a 2# or 1000g forging hammer is a good start. This is a good hammer for a reasonable price -
