I would recommend Micky (M J Lawless) 07930 678989. They have just finished plastering our loft and shower room and had the job done in only two days. Fantastic job, tidy, reasonable rates and friendly too.
Try www.bumperrepairs.uk.com. Carried out invisible repair to body colour bumper.I believe they do paintwork/ dents too. Work undertaken at your home/ business. Price was reasonable too.
