Photoshop image background cut-out/clipping path service?

Hi, does anyone know of a reliable service for cutting out backgrounds (or creating clipping paths) in Photoshop? We have a load of hi-res TIFF images of handguns which have been professionally shot on white backgrounds (I've loaded a typical low-res jpg example), but which need to be used as cut-outs with clean, accurate outlines and completely white/transparent backgrounds. There seem to be plenty of companies in India offering this service very cheaply (£1 per image) but we would prefer to keep the job local or UK-based if possible. If any Hubbers can recommend a company or individual who offers this sort of service quickly, accurately and economically, please let me know. Thanks, Paul
