Hi, I have used a local pet shop before. It was part of a garden centre and they were very good there. They didn't actually charge anything- it was discretionary and any money went to an animal charity. I now do it at home with my partner (he holds and I clip!!) and so far we've not had any slip-ups, fingers crossed!! I always have cornflour on hand though just in case I nip too much off as it stops the blood
