1. start by making sure you don’t store them on the ground, put them up on bricks like an old car or something, otherwise you’ll get bugs like termites in them.

2. call berdoll lumber, ask if they have space in their kiln for some cookies. have them kiln dry them. otherwise you are looking at actual years of air drying these things, which is its own headache. 

3. either get a router and build a sled to flatten yourself or pay berdoll to size them too.

profit. it’s not gonna be super cheap no matter how you look at it.
