Paint job help and recommendations needed?

I don't know what happened? I went to a friends house to hang out and this was last night. There house was gated so I had to dial in so I could get through. I was trying not to scrape my car against the security box, but somehow I did. The only area of the car that has been affected was the drivers side back door. I drive a 2004 Honda Element ex. I live in maple valley Washington and looking for a cheap paint job.

Leave the scrap and take your cheap money and put it towards driving lessons.
