I agree the liability may be high unless you set up something like this - set up a separate entity to run the out-sourced services from in which you 1099 the "employees" and require them to hold their own insurance. Only down side here is your not able to direct the laborers as you would normally due to them not actually being employees. This is how a lot of vacation rental companies handle the constant demands set on them. Definitely not impossible. Cheers
