How to structure money partners

[Frances Martinez]

Hey guys. I am doing a new construction flip in Atlanta Georgia and I have a few passive, money partners that want to invest with me, mostly a few coworkers and a family member. I would like to pay them a preferred interest rate on their money and a small bonus ($1000-$5000) at the end of the flip based on what they put in. I have no idea how that should be structured? I'm pooling funds and making all of the investment decisions. Am I looking at a real estate syndication or some sort of partnership LLC? How much should I expect to pay to set up a syndication?
