Stray cat needing vet treatment

This poor stray cat has been on the street for a very long time, I have been feeding him for a few months and finally caught him and took him to the vets, unfortunately he is in desperate need of surgery as they have found a lump in his ear but don't know the extent of what is needed doing until he is put under, the Rspca have paid for the antibiotic injection but will not fund his treatment any further. So I am asking out the kindness of my heart to help this poor kitty get the love and care he so well deserves. And hopefully he can find a loving home to spend the rest of his days. I am currently looking for a foster/rehoming centre for him once his treatment is complete. Thank you for the time you have taken to read this. Please help him get better. He is currently being treated at companion care vets in sprowston.
