Maybe @Johnny boy can comment, I think he does something similar with the landscaping business.
I'm not a lawyer or an accountant, but IMO, I think you can do this here, but there are big licensing hurdles to conquer and I'm pretty sure the US Taxman will be involved since the $$$ is earned here. The contractor issue also has hurdles as there are tests that need to be satisfied in order to get that IRS classification; otherwise they can audit you and claim you are subverting employees and required payroll taxes.
Everyone's an employee in the states for us.
Except the VA's in columbia and phillipines I don't know what to do about them tbh
