Remember if you are doing anything that requires internet service, you will need to find a good dependable and fast service that you provide yourself. You cannot depend on campground/local internet, because so many even if they have internet, it is slow or not dependable.
That being said, look at your local college they may offer hospitality courses that can be transferred into something you can take with you. Reservations... or maybe you can offer fill-in work for campground.. taking reservations, checkins.. I often see on our state park host website, they will have short breaks between hosts that you might could fill.
