You might luck out. I had a similar incident - worse damage. The guy's insurance company sent an adjuster, and agreed to repairs with no arguements. They let me use the same shop that had done previous work including paint. They even insisted my hanging onto a rental car - which I'm sure they regretted later 'cause it took forever. The only issue was on the final payment - because they eventually decided the rear valance could not be found in a reasonable timeframe and let the shop do the metal work. Labor cost more than, but they had agreed to it. A single letter with a cc to a lawyer at the bottom got that reimbursement within a week. Fingers crossed for you.
