How do I make a legitimate contract in North Carolina? ?

Here is the scenario. A man named Azere is the co-owner of a truck stop. He has given me the opportunity to take over the restaurant located inside the truck stop. The agreement we have made verbaly is that he will provide all the funding for equipment food basically everything that will go into the restaurant that's needed. My job is to handle all the responsibilities of the restaurant besides the funding of course. The agreement we came to is that the moment the restaurant opens I will be paid $10 an hour. The moment the restaurant has become profitable we will split the prophets of the restaurant in half 50/50. So when the restaurant is in the green I will receive 50%. I have never written a contract before so I need some guidence. I was thinking the deal-breaker for the contract would be something simple like.. if I do not turn a profit Within six months then the contract is terminated. Also if I am not attending to my duties and displaying growth within the six months the contract is terminated. Do I just write this stuff on a piece of paper and have us both sign? I'm really Clueless
