I'd suggest also documenting "why" you had the work done by taking some good quality digital photos of the area before painting.

I had some touch-up work done on my '89 before putting the car up for sale. I took pictures of each area that was going to be re-painted before the work was done. I also thoroughly explained and pointed out each of those areas (after) to the first prospective buyer. It was not an issue and that person bought the car.

I did decide to use one of the businesses that do touch-up work for car dealers on location. They did do the work in my driveway and it was satisfactory.
