Anyone know a good ding repairer - Hemel / Watford

[mogv8]

Had a stone hit a rear door, 5p piece size ding but need to have it done.

Want to keep cost down, anyone know someone around Watford / Hemel area you can recommend. I did a search on here but didnt find anything in the area.

I know the going rate to dealers is £35, and punters anywhere from £45 to £65, so looking for good compromise between quality and price.

Thanks in advance.
