Anyone else without expereince?

I'm new to Rover. I don't have a pet, and I don't have a super large amount of experience with pets in the past (just a cat for a couple of years a long time ago), but I would really like to sit (I love pets). Because of my lack of experience and the fact that I can't work during the normal 9-5 workday, I'm afraid of not having any offers. And I don't want to drop $35 on a background check, just to never really make the money back. Does anyone have experience with a similar situation, and if so, was there anything you did to make yourself seem more attractive to owners?
