I'm pretty close to what 4ceps has (and I believe I may have "borrowed" the basis of my payout structure from his setup) but here is my payout structure for up to 30 players:

5 or less players...........winner take all
6 - 9 players................1st place - 67%.... 2nd place - 33%
10 - 14 players.............1st place - 57%.... 2nd place - 28%.......3rd place - 15%
15 - 20 players.............1st place - 51%.....2nd place - 25%.......3rd place - 14%....... 4th place - 10%
21 - 30 players.............1st place - 47%.....2nd place - 23%.......3rd place - 14%........4th place - 9%.........5th place - 7%
