Dog walking in Prospect Heights, Park Slope

I'm not a professional dog walker or anything but was looking to get into it part-time. I love dogs, grew up on a farm and I'm looking to get into individual dogwalking/dogsitting etc. to satisfy my dog-love needs. I work from home so have flexibility to pick up a dog and walk it a couple times a day. Let me know. Just sort of fishing around, exploring the idea.
