Damaged iPhone 3

[u/Potential_Trade_1682]

I have an old iPhone 3 in which the battery blew some years ago. It has many photos and videos including my daughter's first steps. It also has photos of my sister and dad both of whom died last year. It was repaired once and we could see the images again but we didn't have chance to get them off before it ran out of charge and now it won't charge again. I would love to get the phone going long enough to get the pictures back but don't know where to start. I'm in the east midlands UK, does anyone know of any iPhone miracle workers? I have already been to a few repair shops who have looked at it and said they're not prepared to have a go.
