Does anyone know where I can take my iPad Mini for MicroSolderin?

I don't know any one personally but I encourage you to do a goole search with "your town/county/area" and "micro-soldering" and you should come up with a lot of options.

Look locally for a reputable shop. Ideally, you want to find someone local but good workmanship trumps locality. There are many shops worldwide that do this so you shouldn't have any problems finding them. Talk to them and ask how they do their work. Focus on good practices like proper cleaning of boards once completed etc.

If you can't find one locally, then consider mail-in repair. There are several reputable micro-solderers patrolling this forum.
