Currently I only see two badges on your profile. It could be more are pending, but if not I would recommend seeing if there are any more you qualify for, and getting a background check completed. The badges help with the search rankings, which will get you more exposure to Rover users. The written portion of your profile comes across as responsible and professional. I would recommend taking some higher quality pictures of your home (most of the pics are a bit blurry/dark). Bright, clear photos draw people in, and they're the first thing people will see. If they don't like the pictures, they probably won't read your profile. (I've worked really hard on this for my profile if you want to check it out for ideas - all of my pictures, save one, were taken on a cell phone or old model GoPro, so good images don't necessarily need professional equipment.) Especially when you're new and relying on generating clients without word of mouth, you really have to stand out to draw people in.
Beyond that, you'll have to put in the legwork to get the word out. Take your business cards to local businesses that are pet friendly or pet oriented. Hang out with your dog at the park and keep a few cards in your pocket to hand out when you chat with other dog owners. Give some to friends and family members to give to their friends and family members with dogs. Post ads to craigslist/nextdoor (discreetly, it's against their policies)/facebook/etc. It's not unusual for requests to start slowly, so work hard and try not to get frustrated! Good luck!
