Sorry mate you clearly have not looked into the history of SpaceX at all.
SpaceX was set up by Musk, funded by Musk, its literally the only company he's started from the ground. He used the money he made from selling PayPal and Zip2. Bought the 1st Rockets they used with that money. They launch satellites for loads of companies and entities and are something like 40% of the entirely satellite launching capacity on earth.
NASA and US Military are big clients, but thats all they are, clients.
As for not fully set up? thats just nonsense. they are fully up and running and are in the process of developing there next generation of launch vehicles.
