I had a fellow Pro ask me about someone teaching in the club where they have an exclusive contract. Here are my thoughts.
LIABILITY: Others have mentioned this first, but I will reiterate the point.
My first thought was the liability issue. Most operations such as fitness clubs, shooting ranges, or pools have policies for club membership that stipulate against outside instructors unless they are hired or given a contract to operate there. (If your club won't handle this, since you have an exclusivity contract, I'd point out that aside from taking away from revenue to the club in the form of fees, it presents a major risk that an insurance company may not cover
Most organizations want certifications to prove competence and knowledge about risk management.) I'd present it that way to your club owners. An example of some risks include permanent injuries like a ball hit detaching a retina, or how about the big one nowadays, various forms of abuse. I wouldn't let someone coach in my club as a freelancer/contractor without insurance including adding the club as additional insured on the policy, teaching qualifications, and a structured fee agreement.
In your case, if court time is limited, it will over-time directly reduce your income. Let them do their sideline coaching on public courts, or volunteer to help out at schools or the county. If they are really good and you need the help, you might bring them in to assist in clinics so that you can manage their activities.
