Can understand why you would want to get someone to do it as it is it is really easy to knick yourself doing it. I do my own myself and from experience the best thing was to use a good quality safety razor- one of the multibladed ones with a safety guard / slightly recessed blades. Using it dry moving with the lye of the hair, and going extremely slowly and carefully seems to work best. Avoid the cheap razors and the supposed initimate electric ones as they both cut like crazy. Tried a dedicated electric one and in honesty it was the worst for cuts and a toyal waste of money.,
