I'm looking for some fat bodied balsa square bills and some flat sided baits for pressured/cold water to buy. If you have a "catalogue", I'd like to see it. Do you sell? Pricing? 

There are many custom crankbait builders, some of whom frequent here but are not sponsors so won't reply.  I'd do a search, pick a few whose work seems good, and shoot them a PM.  Another good resource is tackleunderground.com, a site for the builder community (commercial and hobby).
