If I had a my reasonable soldering setup and it was the thing that got us to call in a plane to rescue us then I could do it.
If it was a part no longer made and the factory is losing thousands per day I would fix it.
If someone was going to die without the device being fixed, if it needed data for a court case...
If it is a basic piece of cheap consumer electronics I could likely buy a thousand replacements for quite happily then I would do that. Even more so because if those missing pins are necessary (they might be simple power or ground you can pull from elsewhere, not connected or similar) then you will be flying leads to the relevant points anyway which will see more leads have to be soldered to an otherwise untouched board with all the fun that entails in doing it, and possibly reversing it later. Even if you are completely flat broke and have all the time in the world I would still suggest a replacement.

In some cases sure. For a friction fit over the top connector... eh.Find right copper wire diameter, tin it, bend it like the original connector ones -> 2 solder points, could be done by a newbie.
I'm pretty sure that would work, as plastic part does not seems to be damaged, the wire would seat in the notch. Anyways, it would be a 5 minutes job, doing it carefully. Worst case, it's not fitting, and he could still replace the connector.In some cases sure. For a friction fit over the top connector... eh.
Does anyone in the UK on here fix these things?
I don't have the equipment or skill to tackle this job.
Really appreciate your advice.
