Hello - From a new member - Some Questions Also

Hi @Estelle - welcome to the group.
As a sitter, I would say 2-4 months before your holiday is a good time frame to post your listing. There is a large pool of great sitters looking for house sits so the secret is to make yours as appealing as possible. A picture is worth a thousand words so add a good selection of pictures, a couple of your pets and also a good selection of your accommodation - sitters want to know where they will be staying.
You can add a link of your listing onto your profile - This means sitters on the group can see plus give you any advise on improving it if they feel they can help at all.
Here is a link on how to do that.
Good Luck!
