I need some opinion about paint job on my Black G35 2003. Please help me out

Today i went down to the condo parking lot i saw a BMWX5 struggle in front of the remote gate(2 rasing bars). So i back up and wait for him to pass. I waiting 10 sec after he passed the gate, and the gate is still open so then i thought its completely broken since the left bar was broken yesterday. When i try to pass from the right side the bar close down on my car and i have a long white scratch on the right side of my car. So i need some professional paint job on it. Should i go back to the dealer or is there any compateble paint shop that i can go to? How much will it cost? I would probably need to paint the roof+the area on top of the doors.

 

i use www.collisionnetworks.ca - they've done some work on some speedtv shows.
