Saddle and Dual Seat cover repairs and re-covering?

Can anyone please help with advice regarding original seats?
Does anyone know of someone good and experienced who can successfully repair original Lambretta single saddle covers, repair a large split in a Series 3 original dual seat and re-cover original Lambretta dual seats in the North West/North/Midlands areas of England or North Wales?
I have made a lot of enquires locally to me (Merseyside) and a bit further afield and been told that the covers are too thick to repair?
I have some original single saddles and a dual seat I would like repaired (to retain originality) and an ‘accessory’ seat to consider getting re-covered.
Any ideas?
Many thanks in advance of your assistance.
