Where can I find a assignment of contract form?

I am located in Maryland and this is my first wholesale property. I am going to sign the contract with the seller monday morning. Does anyone know where I can get the right form so that I can assign this property to an investor?

You just need a standard real estate contract that says it’s assignable or you put “and or assigns” after you name as the buyer.

Can I find that online? I have been looking but I can’t seem to find the one that says about the option to assign the contract.
sorry for all the questions this is my first wholesale.
