Think Tank

I recently needed a contract for a small project, so I decided to write one myself. At first, it seemed easy. Then I started reading sample contracts and quickly got confused by all the formal wording. I began wondering about professional legal contract writing services. Has anyone here used professional help for a contract? I would like to know how the process worked. Did you explain your situation first, or did the writer ask questions? I am especially interested in whether the final document was easy to understand.
