For NL$25 you would need to play the following:

Bronze --- 117,000 Hands
Silver --- 78,000 Hands
Gold ----- 58,000 Hands
Platinum - 47,000 Hands

These numbers assume that you don't escalate in VIP levels. As you cross each level, the number of remaining hands needed will diminish because of the increasing FPP factor. Also, they are approximations based on the average FPP accruals for the hands I have played at the limit. The FPP accrual for NL$25 was 0.146 VPPs per hand played.

edit to add: these are for full ring play. I think short handed would be about 15% less.
