The difference between a contractor and an employee is how much control you have over them. If you control certain things, then they are your employee if you don't, then they are a contractor.
The biggest question in determining control is whether or not they have other customers besides the ones you give them. Are they their own business/sole proprietorship or do they stand under your umbrella of employment?
You can also have too much control if you decide what they wear (your uniforms), train them (your way), or provide supplies.
If you get so busy that you need help and you call Janet from Janet's Cleaning Company, then she's a contractor. If you call up your friend Jane, you give her all the supplies and a uniform, tell her to go clean for your customers and if she gets new customers that she'll get a bonus. That's an employee.
