After looking at your profile, I see that you offer House Sitting, Drop In Visits, and Walks. The majority of Rover clients need Boarding - although the walking services are growing and they are promoting it more now. However, at the top you noted that you don't have transportation and would appreciate a ride if possible. My experience is that if a client needs one of those services, you need to find a way (some sitters use public transportation as needed) to get to their pets, they are not available to give rides because they are usually at work or out of town and can't take the time to get to their pets (or else they wouldn't need a walker). So, you may need to really think about what you want to do. Maybe you change your service radius only to what you can get to, on foot or other means- whether that's bicycle, skates/skateboard, local bus, a friend that's able to help, or a ride sharing service. If there's not enough demand that you can get to near where you live, the other consideration is to offer boarding at your home, where the dogs are brought to you.
When I searched sitters in Peoria IL, 58 offer house sitting. 57 of the 58 charge less than your current rate of $75, so it appears your house sitting prices are too high for your market. You may want to check your other rates this way.
A lesser critique is to improve the readability of the profile, eliminate negative words, even if used in a positive way (i.e. Not only, Not just) Also, it would help if you posted photos of other pets you've cared for. Even if it's a photo taken and saved by the owner or someone else from another time (not at the time you were caring for the pet), if you cared for that pet, it would be valid to use it - just ask them to share it with you as a file you can upload to your profile.
And since you have experience and see a lot of dogs in your neighborhood, I'd suggest you carry business cards with you, ask pet friendly places if you can leave some, reach out to those who know you for possible referrals, and start conversations with dog people and let them know you're available.
