wow, you do ask for alot... heh heh... well, i guess you can start by drawing one, and see if those printing shops are willing to put it on such a small medium.
They does silkscreen printing on almost anything! but the black picks itself you may have to do a bit of hunting.Try going onto ebay or such to hunt for them! or alternatively you may want to approach local guitar stores to bring in a box of blank picks for you since they have their suppliers.
Hope this is useful to you! and hey do give me 1 of your pick when its done ok! i deserve it hor! haha :twisted:
