Legal contract advice need help please

What SaintJ said. And non-competes, in my experience, do not usually address issues of compensation.

What you are talking about is the terms of your contractor relationship. Employing someone on a contract basis AND having them sign a non-compete basically makes you an employee of that company and potentially makes him liable for a bunch of employer liabilities that are often avoidable due to the contractor relationship (things like wage/hour laws, employment taxes, citizenship paperword, etc etc).

Just my (non-legal) opinion, but I would think your employer is in a pretty precarious position, regardless of the wage change. I also think you would have a hard time proving/fighting the verbal contract aspect and it might not be worth fighting, but you certainly have enough on him to get you out of your noncompete, and much more if you feel like pursuing it. Employment law can drag out though.

(also, insert the rest of the usual disclaimers here, including the fact that I am not a lawyer, and I have only been to Wisconsin once, and I was drunk the majority of the time).
