How can I hire contractors for someone else's home?

[Vincent A Tomasello]

What's up guys! I am currently scaling a new business around property management but for homeowners in their own home. Do I need any special contract in order to find, hire, and pay a contractor that does maintenance on someone else's home? Think of me as like a broker for contractors and homeowners. I figure property managers do it all the time but I just need to know if there is a specific/necessary legal process to doing that for someone else.
