Do you have a picture of the damage? If you have just curbed it, meaning you scraped the side of the rim and you didn't bend anything, you can get it fixed easy. You just need a guy will sand down the rash, apply bond-o to it and let it dry, and then fill it in with the proper color wheel paint. You can do this yourself, but it will probably come out looking much better if you have a professional do it for you. Just go to yellowpages.com and search "Wheel repair" for Manhattan, NY and I am sure you will get lots of results. Repair cost is between $80 and $300.
Btw, what model year, color, etc. are you? I am in NYC a lot.
