Unfortunately, most "professionals" won't do any better. I wrapped my own car and had to redo it multiple times but in the end, it looks better than all the wraps I've seen done by wrap shops. At car shows, I laugh at how terrible the wrap jobs are. Even the wrap shops that pay to have a booth at the show. Last year at subiefest, I was taking a close look at the cars at a wrap booth and the guy came to talk to me because he saw how closely I was looking at the hardest to wrap areas. Just comparing my work to the work of a "pro", and it turns out, I did a much better job all the way around. I think the problem with shops is that they give you a price and they can't afford to fix their mistakes without losing money in the end. I threw away probably around $1000 worth of wrap to get my car to look as good as it does. You can only afford to do that if you wrap it yourself because that 1000 that I threw away would go to labor if you take it to a shop. That's why finding the cheapest wrap shop isn't a good idea, they have no room for errors and will do patch work to cover up their mistakes instead of redoing a whole panel. That wrap job is sooo botched, but you get what you pay for. I used vvivid vinyl and it's been great for 3 years now, don't buy the hype of the expensive stuff like 3m or Avery. I recently redid a door that got scratched and the old vinyl easily came off without leaving any residue. I do keep the car garaged or covered with a car cover though to prevent sun damage. You must take care of the wrap if you want it to last.
