I'd love to see some sample work. It'll be a while, but I hope to make some bitcoin sites eventually and I'll need logo help.

I don't really have a portofolio but you can hire me, I'll do the work, out of passion, and if you like it you can pay me. If not, you'll see what I can do but cannot use the logos since I'll post 'em as .jpg

Actually that's a rule in logo making. You won't get paid until the client is satisfied. Altrough I'm pretty sure nobody will be disappointed.
