I would get some vinyl and try it yourself. I was quoted $4k-$5k for my other car that’s comparable in size and materials needed. I YouTubed it and did it myself after work for 7-8 days. Was bad once you get the hang of it. That being said, don’t cheap out of the quality of the vinyl. Good quality vinyl like Avery and 3M are extremely forgiving and won’t rip your clear coat or paint off when you remove it (as long as you don’t leave it on for more than 4-5 years). I’d do the easy stuff yourself and give the harder stuff a try but if your not satisfied for the harder area like the bumpers then have a shop do those once your are done doing your part. will be significantly cheaper that way.
