I don't know why you're downvoted. People act like lawyers do something magical, but if you have been around business contracts for 2+ decades you can certainly draft one and then just have a lawyer review if you want.
In the US in particular, topics such as law, accounting and medicine are heavily gatekept to the point where many people believe that unless you're a lawyer, accountant or doctor, you shouldn't even be able to discuss these subjects in any meaningful way.
