When is a lawyer needed when setting up an independent contractor agreement?

Please answer a few questions, so I can better answer your question. 1) Are you going to be the person that is the contractor or the person who is hiring the contractor? 2) Is the project/job the contractor (or you) is going to be doing a temporary project or job or is it part of the regular operations of the employer? 3) How will the contractor (or you) be paid - by the hour; by the day; on completion of the project? 4) Who will provide the supplies, materials, equipment? 5) Who will supervise the work?   Let me know these things and perhaps I can give you a more intelligent answer to your question.
