There are mobile interior repairers, I have used “Automotive
repair systems” before but I don’t know if they cover your area.
My damage was not as extensive as yours, they fill it with
some sort of plastic paste then spray it with a leather looking spray, they didn’t
have the colour match for my car so had to send a sample away to get the right
colour match, but I was impressed with the results, and you had to look fairly
hard to see the repair, but as I said my damage was not as bad as yours. This was
a few years ago, I think it cost around £80
its a long shot but you could try a breakers for a replacement panel.
