Paint you get what you pay for ! Sometimes !!
You can go to any number of people who will put paint on your aircraft, depending on the shop it will fall off sooner or later as the paint underneath fails. Probably the best of the shops that don't totally strip the aircraft would be Falcon Aviation on Malta. If you are looking for an inexpensive job that will last quite well then they are worth talking to.
At the top end of the market would be Mick Allen Aircraft Resprays at Turwerston UK. I have had two aircraft painted by Mick and have never regretted it for a second, he is not cheap but if it is your intention to keep the aircraft you will find him inexpensive as it will probably be the last paint job your aircraft will ever need.
