I got my contracts off that book called "Real Estate on Steroids" by Jackie Lange, its on Amazon for a few buks.
The Purchase Contract and the Assignment of Contract is included. Simple 2 pages. They work for any state, I did a house in Maryland and Nevada an one in Mongomery. Getting the property tied up quickly with a signature is most important, and the Title company I suspect might write it up in a more formal and standard contract.
This is insane how simple a contract can be. My Mom wrote up a simple purchase agreement for amount owed, no money changed hands, on a napkin at the restaurant with a distressed seller, on a nice house, which we inherited.
Just jump.
