I know in the other thread you said that you wanted to do all kinds of chips(clay, ceramic, etc) but I think it'll help if you give more info about where you want to start first. i.e. clay spotted cash game chips, spotted inlaid or hot stamped tournament chips, ceramic cash chips, etc.
There is a member on here named chipshippie that does design work. You could start by PMing him.
There's also some sites that'll work with you to make custom designs. Or you could put out a classified somewhere, find a graphic designer from your city that'll work with you. This way you'll be able to see progress and give first-hand feedback.
