Wholesellers Agreement/Contract in TN

[Wane Tango]

So I am ready to start making deals. I have talked with several professionals on here and I have mustered the confidence to start talking to prospects and potential buyers. I have a good idea on how the process will flow, I can see all of the moving parts to structure most of the deals that I am tracking, but I have one seriously important tool missing from my tool belt. The actual contract I would get a potential seller to sign when I do strike a deal. 

I talked to all of the local lawyers offices in town and non of them deal in real estate so I kind have been left out in the cold since then. Does any of my fellow Tennessee wholesellers have some insight on where or how I can get a usable contract?

A friend from a local real estate agency let me borrow one of the contracts that their company uses but in no way could I use this contract. It just lets me get an idea of the verbiage.  

Should I seek out a real estate lawyer in TN to write one from scratch or is it reasonable to think that another whole seller would let me use their contracts. I dont want to reinvent the wheel here but I also dont want to step on anyone's toes and make a faux pas among my peers here.  

Any input would be greatly appreciated!
