We believe you have lacked everything, the parts. Simply put, what you are presently telling me is absurdly stupid as it were, as if you were telling me you had a car that reached a top speed of 60mph and that by adding a second engine you can now make it 120. If you have 3 programmers or more then you'll eventually run into problems. In Transition From Freelancers to Managed Teams, key people to add are project managers, sales people and support people. That will require that you must specialize and get people in to do databases, infrastructure and certain languages. One day you will need offices, you will have to pay upkeep, medical, benefits, etc..
