What further steps should I take in getting contacted about my first sitting, and how would I know when I have been contacted?

Your background insofar as taking care of pets is very good and should be attractive to potential customers. However, you should ask friends/family or other people for whom you've watched pets to write you a few testimonials. That would provide a little more reassurance to potential Rover clients since the only services you offer are ones where you go into a person's home.

Here are instructions for getting testimonials:
