Merak-
This company is local to me and have done a couple of bicycle saddles for me. Can't fault the work and wasn't overly expensive from memory. They may do postal orders but I've no idea of cost. Might be worth dropping them an email - at least you will know.

Find a local upholster and see what material they recommend. Are a London local?
