It depends....do you want to run a shop...if so, hell yea you can make it well. Id say the most money comes from a good location and a custom shop. Tinting does make a shitload of money. You can get a tint cutter for like 4-5000 bucks. It updates the cars every day into its database. You enter in the car you want...enter in the windows to cut, and it cuts them out PERFECT every time. I was almost thinking about getting a loan....do you realize how much money you could make with one of those...you could tint 10+ cars a day for 150-220 depending on what windows and what tint they want....if you have 2 guys that can tint...thats $$$$$$
