A pooper-scooper can make $40 to $45 per hour if he works with an average of four clients per hour, says Matthew Osborn, former professional pooper-scooper and author of The Professional Pooper-Scooper.

Some companies take the poop with them while others double-bag the waste and leave it in the client's trash bin. Weekly visits typically continue until the client contacts the company to cancel services, as most scooping companies don't have contracts. How do commercial pooper scooper services work?

It's easy to start a pooper scooper business and (apart from one obvious aspect of it) there are few downsides. There's a market for pet waste removal pretty much everywhere. It doesn't cost much to get started and it's an option for entrepreneurs of all ages.
