Paint job prices are regional pretty much. Price ranges mentioned are fair for a non-custom color paint job that’s straight forward. Honestly, paint materials should be under $800-$1,000 depending on paint brand used. The rest is labor for the most part. To properly prep and repair a vehicle for paint takes time and skill.
Always ask about the prep process..taping off, sanding, repair of dents(PDR vs other methods that may require use of bondo), brands of paint and clears used, how many coats, WARRANTY?, view work they currently have in progress, pictures of past similar jobs completed and if possible if those customers would be willing to let you view their vehicles.
The issue with jobs like this is that they are time consuming. Shops can knock out a few insurance fender benders and make just as much money with less effort. So, the shops charge more for the time tied up in these type of projects and that’s why the prices vary—along with the quality of work. Definitely check for warranty on the work performed i.e., issues with clear, paint premature fade..
Good luck
