Hopefully you take this kindly..... I'm just going to list things that jumped out at me.
Need more pictures! Right now you have 3.
Rates are scary low. Especially for California. It makes it seem like you're inexperienced, or don't know your worth, or might have sticky fingers and pricing doesn't matter.....none of these are true but that's the only reasons I can think of why you're about $20 less than the competition.
Why put that your pets aren't friendly? That puts both of you in a bad light. Omit that entire statement. Also I notice you don't have profiles created for your pets? It would be nice to have that since you mention them.
House sitting you don't do Saturday night? That will greatly limit the requests you receive because most people do weekend trips.
You list you can do injected meds but not regular meds? Or senior dog care? I would include those. Also do the "Dog 101 Quiz" so you can add that badge to your profile.
Ask more people for testimonials. They don't have to be ones with pets. Just anyone who can say something about your character and abilities.
Hope that helps, best wishes!
