Glad you asked -- I happen to sell an ebook about starting a home-based pet services business! It's an unusual one... it's all about how to start your own professional pooper-scooper business. I've been 25 Years in the Dog Poop Biz; 10 Years picking it up, and 15 years helping others learn how to start their own businesses. I've sold thousands of copies of my book, and I know that hundreds of people have started their own businesses from the information. It's very gratifying to me to hear from them and read about how happy they are to be their own bosses now.
I sell the book on my website, Pooper-Scooper.com, but you don't have to buy the book to get a lot of valuable information on the site. The Scoopers & Friends discussion board is FREE to use, and it's an online resource where people in the business all around the country discuss the ups and downs and ins an outs of the dog waste removal service, including the occasional query about cleaning cat litter boxes on the side.
