Specialised film maintenance

I bet there is nobody on this forum that offers a cleaning maintenace contract of solar films by specialised tinters like ourselves.
It's a market I've often thought about that could be had for the asking because it currently is not done.
A dedicated tint cleaner could pick up new tinting work, new areas to be tinted, staff homes and cars or old film redone.
Anyone else thought about this or am I the only one?
Charge a fortune too so you're not compared with ordinary glass cleaners.

It would also be another good way to get into contracts that you might have lost in the initial bid.

The window cleaners here charge too little to make it worth our while.

I was really meaning keeping the cleaning within your own business. Not using outside glass cleaners because as sure as anything they will cotton on to the money to be made and seeing they're half way there with cleaning, they'll be your next film competitor.

I am located where tinitman is... these guys here have no idea what to charge. Almost every industry around us us charging too little for what they do. when we moved here, my wife was suposed to be making 60k a year, but after looking through the job market and seeing what everyone else was paying she had to settle at 40k. That is what happens to a city that brings in 70% of it's labor from areas of the country that have 50% the cost of living that we do here. It is picking up, but things are still very Low ball around here. I just ran into a guy charging $3 a square for comercial. Killing me.
