Only thing I would mention, Rio Grande has catalogs for materials and also for tools, which they will send to anybody. And I'd carefully but skeptically peruse the tools, because there can be some unexpected time-savers. If you find useful tools, you may not want to buy them but check around for them among local crafters, who tend to be a network of nice folk. Also-- equivalent tools from other sources. For some reason if people think you're crafting or even just arting around with a tool, it costs more than the same tool for other purposes.

I wouldn't go to any lengths for wholesalers. You might not stay in the same mode long enough to make it worthwhile. You may want to change things, follow new ideas, you don't want to feel stuck with many big commitments in materials, just enough to get the ball rolling. Happy crafting!
