Property Management Start up

[William Fields]

I own a couple houses and love real estate. I figure the best way to work in real estate full time while I'm building my portfolio would be to start a property management company. I have been lining up potential clients with the intention of launching this year. I took a part time job as a maintenence man at a company that owns about 60 units in my town and a few hundred around the country. 

The only problem I have is trying to find all the responsibilities of the management company vs property owner. What does the fee pay for versus what do I need to charge the property owner for. Any advice would be great. Thanks guys
