Wholesaler just starting out

[Somer Wheat]

Hello,

I am brand new at wholesaling and was looking for some information on where to get the contracts. Are there 2 different contracts (between seller/wholesaler, and wholesaler/buyer)? And where could I get these in a legal, professional way? Also, who actually puts down the earnest money on a wholesaling real? Should I expect to do that after I get a deal under contract, or should I ask the buyer to? Thanks for any help!
