Well hopefully someone local to your will chime in with suggestions on where to go but offhand I'd say start looking for a nearby computer store with a repair department. Angie's List is another place to look. Do NOT go to a place where you just drop off you phone and tablet leave it, from what sounds like you really need to stick around and make sure your personal data gets backed up. Don't just rely on someone at a service desk promising you they'll back up your data, sit there while it's actually being done. Once it is, then leave your devices and let them do the Factory Restores. And be absolutely sure to implement and maintain some kind of online backup solution so you don't have to worry about losing important data.
