Hi @Timmy … we lived in Bocas in Panama for 3 years before setting off on our travel / house sitting adventures, and Ian built an off-grid property on a small island. Our view was a lot like @ElsieDownie 
Almost all of the sits we did to start with were off-grid in Central America (Panama, Guatemala and Mexico) as well as in Australia/Fiji, as it felt like something we could specialize in for a while and get some pretty amazing, unusual sits with equally special pets. We found once in place, lots of referrals followed particularly when word got around. So networking in the expat communities is a great way to start… and to spread the word about TrustedHousesitters!!
Here’s an article that my partner wrote about off-grid systems, which might help you prepare for some situations (you’ll see our little off-grid home in the featured image - often wish now we hadn’t sold - it was a good hideaway):
Enjoy your hunt for sits!
