Hi @Tambourinewendy , Welcome to THS and the forum! I wish you much luck with your move. The area sounds beautiful and it should appeal to many sitters. @Peg has some good pointers. You can also take a look at these topics:

I would encourage you, once you have created your listing, to add it to your forum profile. Experienced members will then be able to give you feedback to make it shine. Here are the instructions:
How to add your listing or profile to your forum profile
I would also suggest perusing other owners’ listings. Detail is good, such as your pet gets walked at 8 AM, 4 PM and before bed and eats twice a day, also any personality quirks, but minute detail should be discussed in your phone or video chat and go in your Welcome Guide, the document that is sent to your sitter once s/he is selected. Otherwise, people reading your listing will get bogged down with the small stuff.
I hope you enjoy this lifestyle as much as I do!
