Rebating and negotiated commission rates are totally different.

The broker earns the commission from the insurance company, the usual commission rate on 91 & 135 policies is 15% - however the broker can negotiate the commission down or even remove it completley and charge a negotiated fee from the client.

Rebating is when the broker shares a portion of the commission earned with the client - very illegal - except in Florida, for some strange reason.

The time in the aircraft look good, so I see no problem finding coverage, the insurance carrier will demand that you complete school in M+M prior to flight ops.
