With all due respect, those figures are quite meaningless without a great deal more information. Take any bunch of people, impose some basic rules to prevent deliberate sabotage and you'll pretty much get a normal distribution in returns. It therefore comes as hardly any surprise that you'll have a small number who are profitable from day one (balanced by an equally small number at the opposite end of the distribution who do appallingly badly) The low transaction costs available by trading through a firm such as yours actually makes it even more likely that people will do well over the short term.
Even using the phrase "trading profitably" is a bit of a non starter, what does that actually mean ?, I assume it means achieving a reasonably consistent equity curve with a positive slope, with drawdowns within some agreed limits, rather than just a positive account balance, and I suspect a prop firm would have a far tighter definition.
I'd be stunned if you can teach this stuff to people in 3 months, and I'm not even sure why you'd even need to or want to.
