Hi Deni, Look in YP under signwriters, I think they are under there. Got mine done in Ktees in Fareham -cost about £10 to set up text and then approx £5 per item (the more you have the cheaper it becomes). They look very good - used to use them as well when I worked at Doves Ford.
Try Alexanders not sure if they have once where you are.
Have a look in your telephone book (yellow pages) they can embrioder (not sure if i spelt that right) logo,names etc you can also purchase your uniform from them they supplie alsorts as well as hand towels for manicures they are really cheap they can put your company name on your towels too.
I got mine fom Florence Roby, they are a little on the expensive side but they wash really nice. I have had then about 2yrs now and they look as good as new, so sometimes paying that bit extra pays off in the end. Word of advise though!!!! i have two white tuics and the buttons are fabric coated and have started to look a little gruby and i cannot get them clean, the next time i buy some i will get them with a pearl finish.
