Need help with assignment of contract

[Lawanda King]

Hello everyone! i hope that someone will be able to assist me with filling out the assignment of contract form.  This particular contract starts like this:

The undersigned assignor, having executed a contract dated ____________ between __________, contractor and ________________contractee for a purchase price of $ _____________, concerning the property described as _________________________, hereby assigns all rights to said contract to _____________________, assignee in exchange for compensation in the amount of _____________________________, of which ________ non refundable earnest money deposit which shall be credited at closing as part of assignee's compensation costs. Deposit shall be held by assignor until closing.

NOW WHAT I NEED TO FIGURE OUT IS WHO IS THE CONTRACTOR AND WHO IS THE CONTRACTEE...I WAS GUESSING THAT THE CONTRACTOR WOULD BE MYSELF AND THE CONTRACTEE WOULD BE MY MOTIVATED SELLER BUT THEN IT LOOKS LIKE IT COULD BE FOR MY END BUYER. PLEASE ASSIST ME..THANKS!
