Let me suggest another route to take.

You can play a T2000 tournament with starting chipstacks of:

16 x $25
16 X $100

This would total 480 chips.

You use the remaining 20 to get $500 chips. 12 of these will be enough to color up all the greens (buy some $100's with them from the big stacks, then use the $100's to color up the $25)

The advantage to this is that you could cut the chipstacks in half and hold a T1000 tournament for 30 people with this set as well. This gives you a lot of flexibility if your game grows.

Use the WSOP structure for the $2500 buy in or below hold'em tournaments.
