In TX, you cannot be a subcontractor w/o first being a licensed contractor.

To hire anybody other than an employee, they must be licensed as a contractor. Having a JW license or even a masters license does not make them a contractor. Contractors are required to have workers comp, liability insurance etc.

If your insurance company finds out your subcontracting out work they will require to see your sub's insurance. If they don't have it, your insurance company will bill you for the added risk to carry the subcontractor.

It's unlikely you'll have enough work to start a business with serveral employees on day one. I wouldn't want to do it even if I could have.
