Independent contractor? Looking to go into business wit MD

[LmurphyRN]

Hi! I am wondering if anyone has any insight on becoming an independent contractor? Going in on a business with a friend/doctor and wondering how that should work? How should I be paid? I was told the LLC will contract with me to run the business for 50% of profits. How can I best protect myself? We are in Georgia and business involves lab testing. Thank you!
