How do I become licensed, bonded & insured as a pet-sitter in my own home?

You should call your local government to see if you are required to be licensed to provide boarding in your home, some localiies don't allow this at all. I see you are in Gainesville, I'm in Lake Ridge and PW county doesn't require a license. While Rover provides basic insurance it leaves the sitter without adequate liability coverage so lots of us purchase our own independent insurance, this link shows you a few of them http://petsits.com/petsittinginsuranc... Bonding is only required if you have employees or other independent contractors working for you.
