I have some paint damage to the bottom o/s edge of the boot door that needs sorting (about 3" long), it has been catching the top edge of the rear bumper after a bump in a car park a while back.

There is also a stonechip on the bonnet.

Try ChipsAway?  They will come round, assess the damage and give you an estimate.  Chat to the guy and find out how long he has been doing the job.  In my (very limited) experience, the guy who did my neighbour's car was damned good.  From Googling around, I get the impression that some of the less experienced ones are awful - possibly like the curate's egg, good in parts (of the country).
