I recommend that you do some reading on pouring and mold making before you jump into the game. I'd also recommend that you pick out a mold and buy it, pour some baits, then decide about making molds.
The best place to learn about all this is tackle underground.
Check out Lure Craft, Jann's Netcraft, Bear's, Barlows Tackle, just to name a few to see what they have to offer.
It is quite a hobby to get into. I make baits all the time and my own molds. It really gets addictive.
