Looking for a reliable sitting to help out frequent travellers

My husband and I live in Louisville, but have frequent trips out of town due to family located in the Northeast. We recently adopted a Senior dog named Archie and are looking for a reliable sitter to help us out when we are away. We are hesitant to send him to a boarder as he spent several months in a shelter and as a result has some separation anxiety. We also have two cats that are very easy.
