Need help with front-left quarter panel
 

Judge me as hard as you'd like. I was driving my brother's 2001 S2K and dinged up the driver's side quarter panel by spinning out into a small street sign. No damage to the wheel or door, but the ding is about the size of a football. What are my options? How much would it cost to buy another qtr panel and have it sprayed and welded on? Thanks in advance.
