Suggestions on a good program to help increase velo?

I am looking to hit 90 and hopefully more by spring of '08, my graduating year. I don't quite know what I am at right now, but fall of '06 I topped at 87. Before you guys say velocity isn't everything. believe me, I've heard it before.

Right now I am looking for a good program that I can use in the off season to put me over the top.

Thanks for your advice!
