We have 1000 chips which is more than enough A set of 500 will probably do.
Your order is pretty accurate although blues do not do well in poor lighting as they can get confused with black.
At our games,we use whites at $50 and reds $100, with green at $500 and black at $1,000. If you could get another color you could use that other color for $5,000 if you wished.
