Any ways to get rid of rust without paying a high price at a body shop?

I have a little rust on my passenger side door. I was wondering how i could do a nice job getting rid of it without paying an auto body to do it.

thanks

sand it down and some of the area around it, prime it, paint it. you can use spray paint as a temp solution that matches your paint.....can get it at a paint shop in a can.

Thanks alot. I should probably try to get some help from sombody who knows what they are doing.
