Keep at it. You may just need some persistence. Have any of the people you have trained gotten jobs? Do you have any kind of network to leverage? Can you follow up with your client and make sure they are satisfied and if so do they know others that could use your services? I would scrounge up paying work wherever you can get it and use that to build from rather than churning "Tutorial Hell". IMHO, delivering stuff worth paying for is more valuable than building skills through tutorials. Not that both aren't worth doing, but I would be biased toward things you can get paid for while you build your skills, network and portfolio.
