@HilaryAnn , You’ve received good advice from @Lokstar . If you make an edit to your listing, such as one suggested by @Twitcher , it will move your listing to the front of the search results. And/or if you remove and repost your listing, it should trigger notifications to all of the sitters who have favorited your listing.
I also suggest adding your listing to your forum profile: How to add your listing or profile to your forum profile By doing this, you’ll reach forum readers who may be interested in applying and you’ll be able to receive helpful feedback on the listing itself.
