New with some questions

I have been doing a lot of research, looking at others websites, working on pricing, just basically trying to do my homework. I am trying to do this starting out small, for extra money, evenings or weekends. I do have a few questions though.

1. It is realistic to think I could start out like a kid starts a lawnmowing service, getting a few clients at first, and building from there.

2. I don't want to be a waste removing service, but a pet clean up service. I would double bag it and leave it for the customer to take care of, just as if they themselves would of cleaned it up. How many do it this way....just clean it up, don't remove it.

3. Are there regulations with this business? Where do I go to find them?

4. What service works the best, or do customers prefer, 1x per week, 2x per week, biweekly, monthly. What is the majority of your customer base.

5. What do you use to disinfect your shoes and equipment with between each home? Where do you buy it?

6. Insurance, where to go to look for it.

I have read many of the post, and will continue, but hopefully someone can help me out on these questions. While I think this is a novel idea, as there is nothing in our are, we are a rural town, with several little towns within 20 miles. So truly not sure how it would all work. Still in the planning stages. Thank you for any advice you can give me.
