Then he did a major renovation to the second side of the duplex I live in including installing a shower, laying flooring, and supervising other employees such as the plumber and electrician.

@Daniel Fridrij to manage property in this state you have to hold an active real estate license...to have an active real estate license, you have to work under the supervision of a broker.... 

I think a good broker is a mentor that helps you learn how to develop your own business while providing you supervision and keeping you within the boundaries of the law and good customer service.

They must work under the supervision of a Broker.

It's the knowledge, experience, the dedication I put into reading, studying, and learning the market that puts us in the position - adding me performing supervision, contacting, building & maintaining a solid relationships and team with reliability and high quality only justifies it even more. 

Looks perfectly reasonable in scope.As for PI from GC's subs....complex topic, but 1) make sure the GC has an active insurance policy, naming you as additional insurred (verify day of job and randomly through out). 2) have GC sign affidavit that they will adequately supervise their employees/contractors. 3) have a policy yourself that covers contractors. 

Also possible penalties for the Broker of record due lack of supervision.   

I think I wantto keep him but I wish I could find a nice way to reduce the paddedhours and helper use without driving him away and without havingsomeone supervising him.

Alternatively, you could pay him a percentage on "top" of the work he supervises to get the house in shape.I would also think a "lease-up" fee would be appropriate. 

I actually have GC that is supervising the rehab work.
