This is a very complicated area which would require much more detail and discussion with an attorney to reach a decision. Therefore, I strongly suggest that you consult with a labor/employment attorney as soon as possible.
There are subtle distinctions that can make a difference in whether someone is an independent contractor, contractor, or employee. With contractors, the contract is the critical indicator whether the company has a right to control the work or not.
I again state that you should meet with an attorney to get legal advice in making your final decision. Good luck!
