Hello @gillS and welcome to the forum. This is a great place to get answers from our seasoned members who can help you with most anything that might arise.
Your question has been asked many times and I can attest to the fact that short sits are usually quite easy to fill as are the longer ones. Short sits are great for those sitters who are transitioning from one sit to another and can easily fill in a weekend or even longer when waiting to start their next one.
I took a look at your listing and can tell you it is quite thorough with you covering most questions sitters might have. You have given great info in regards to the local area as well as your adorable three pups habits and needs. The only other thing I can think of right now would be to add your member listing to your forum listing so it is easy to find and that much easier for potential sitters to apply and give feedback. To do so, just click here at How to add a listing or profile link to your FORUM profile - Welcome & Getting Started - TrustedHousesitters Community Forum and follow the easy instructions.
Good luck with all your future travels!
