I take it no-one turned up? Thats a shame, you are offering your time for them and your expertise.
Perhaps in the future, try not to be so 'demanding' and autocratic of the demands of potential students? This is not an observation but a criticism (instead of the norm) i`m afraid, hence my original post about 'who is this guy?'.
I can help you establish something if you would like, but to be frank, you'd need a complete overhaul in your approach.
Good luck.
