Do them yourself m8, its easy and cheap enough, you will need to rub the rust down with aluminium oxide paper use 60 or 40. Get body filler in the holes wait till it goes hard then use wet and dry to make it smooth. Use 120 - 240 then use 400 - 600 then use 800 - 1500 to finnish it off, will be smooth as glass when youve done that. then spray over the filler with primer when the primer is dry spray over that with paint matched to your car (colour code will be on the vin plate) finish off with a coat of laqure. Will cost 30 quid tops. I had loads left over after doing two rear arches.
