Recently I've focused on subcontracting as opposed to prime contracting. You are licensed for both and can choose to do both if you want to have a bright future. The difference between the two is control.
Make the switch from construction to service work
As a subcontractor you are at the mercy of whoever has the prime contract. As a service provider you have the prime contract (usually spelled out on your invoice), and all the control necessary. Are you capable of, or do you even want to, switch to business owner rather than stay a simple subcontracting drone?
