Welcome to THS and the forum!
Normally you are asked to put your listing link in your profile, rather than linking it in your post. Here’s how to do that. How to add a listing or profile link to your FORUM profile
I just checked out your sit. Looks like you already have 4-7 applicants so hopefully you are well on your way to finding a sitter!
One suggestion: I wonder if it’s would be possible for you to offer a vehicle for the sitters to use? That might be one way to attract more sitters. The cost of rental cars is very high right now.
