High-quality painting and collision repair work are very rare commodities. If you find a shop that has a well-deserved reputation for such quality work, expect to pay a lot more than the "usual or customary" fees charged by shops that are contracted by auto insurance companies. It takes time to do this sort of work properly, and time is money.
