This is a technical support forum sponsored by Apple. We can't discuss gray or black market repair services.
There may be one out there that can help you, but be prepared to pay at minimum $300 or so with no guarantee of recovering anything at all. Also beware of those who claim otherwise. Several of the most vocal 3rd party repair operations have recently been "busted"... having large shipments of illegal counterfeit parts intercepted by Homeland Security. Not exactly a good sign when it comes to how far they can be trusted.
Apple will NOT repair a liquid damaged phone. The only option they will offer is out of warranty replacement.
Apple does not offer data recovery services.
If you had iCloud backups enabled, and had sufficient storage available in iCloud, your phone should have been backing up on a daily basis when connected to WiFi and a power source. Your photos may be backed up and you just don't know it.
If that's the case you can just get the phone replaced and restore the iCloud backup.
