12 U rep off season pitching/throwing program?

So I live in Toronto and my team is now moving to minor Peewee , which up here is 50 foot mounds, 6 foot bases and pick offs and lead offs.

I really want to spend a lot of detail on pitching this off season but the conditioning to go along with it. We have two gyms a week until april so there is lots of time. Its me and a few coaches and essentially everyone should be taught pitching but obviously some will excel more and be more of a starter type pitcher.

Can anyone suggest a good program ( even if I have to pay for it ) that would work for my situation? I am definitely going to do 6oz and 4 oz along with regulation size for a regular twice a week throwing program but just need advice on an actual set program.
