Mookie:
Labels are probably the best way to go. However, if you don't have a recessed center in your chip, the labels may make it more difficult to stack them. Since the 'clay composite' 11.5g's aren't the best for stacking anyway, you may not be happy with the result.
Nonetheless, if you're looking for advice on how to label, check out this site:
Label Design
By the way, the whole site is great for information about chips.
I'm pretty sure that you'll find that having someone do the labels for you will exceed the cost of the chips. In fact, it may be cheaper for you to buy a complete set.
In this regard, Nexgen may be the best value if you intend on labelling (they have a recessed center, so the label fits in).
I don't think we're supposed to post ads, but PM me, I'll be happy to share a couple of sites I've found that will customize.
