Hi @Erconwald
Welcome to the Forum!!!
There’s some really good advice in this discussion already, I thought i’d also share this discussion where pet parents have shared some advice on welcoming a sitter to their home.
Just to echo what has already been said, Trusted Housesitters is all about being mutually beneficial experiences. You’ll find the right person for you, your pet(s) and your home, the key to this is often good old fashioned communication. 
There’s so much fantastic knowledge and experience in the forum and we’re always here to help.
