Earlier quoted context omitted.
Did you have a lawyer to represent you? That's their job... to make sure that the contract you're signing is OK. Actually reading a contract without knowledge of the law, case history, and background can get you into just as much trouble as not reading it at all. That's why you have lawyers review important contracts.
How much would it cost to get a lawyer to go over some contracts with you and let you know what's in there that you don't want? I imagine it depends on the type of contract, but a guess would be helpful.
If it's a three page contract, and you don't have an existing relationship with the attorney, you'll probably just be charged a flat fee of a couple hundred bucks, or nothing, depending on what sort of other business you might bring in.
