My car hit the curb from the bottom and now started making a loud vibration?

I own a 2013 Honda Fit and just recently I hit a curb from the bottom and after that my car started making a loud vibration sound whenever I start up my car or press the gas pedal. Yes I know it was my fault because I was parked and was ready to leave but did not see a curb I front of me so I drove forward and that's where i knew I messed up. Back to the problem, I had my brother checked it out for me and he said that I bent a metal frame on the bottom of my car and he won't be able to fix it cause he don't have tools. I want to take it in to the shop to fix it but wouldn't know how much it would be or know what the problem is. I don't know much about cars so what could have happened to my car?
