Go to here to order real custom Paulson chips:
http://www.trademarkpoker.com/paulson.asp
Scroll down to the bottom for custom ordering info. Minimum order is 100,000. If you want quality, these are the best.
A good second choice is ASM:

They did the chips for the movie Rounders.
I hope this helps!
