where can i get quick ER replating?

Its come to the time i need to get my ER (white gold) replated, i know this thread has been done before but does anyone know places that do it in a day or 2, as i have asked in all the main jewellers and they send it off for a couple of weeks. my friend found somewhere but that was in wales, i'm in hampshire! Hope you can come up with something......ta!
