Real Estate Attorney ~ Contracts

[Andru Sexton]

Can I contact a Real Estate Attorney and tell them I would like 

A Purchase Agreement & An Assignment of Contract?

ON TOP of that, could I tell them the contingencies I would want inside of the Purchase & Sale Agreement?

Reason I am asking is because some of the contracts I have found online have WAY TOO MANY contingencies and I think that would scare away my seller. 

(OR is it possible to cross those contingencies out, or get rid of them somehow?)
