Shot in the dark here, but I am guessing $97-$147 is not what you want to hear given the enormous earning potential this has for the motivated student. Those real estate courses and seminars cost an arm and a leg, but what they do have going for them is testimonials from people other than the author, which you might not.
I would think that a tiered model that constantly up-sells would work the best, the serious will keep paying, the unmotivated or inept will drop out and not come screaming for a massive refund thereby putting you on the defensive - which seems to happen here on occasion.
I think you are opening yourself up for headache if you offer coaching to everyone right off the bat.
Side note. MSNBC or maybe Newsweek just ran a very interesting article on possibly the most disgusting practice I have seen yet, something about researching foreclosures and finding out who has equity and getting them to sign over thier property, taking out loans, then evicting them. Those people should be shot (some will be). The interesting part of the article, was that they said that those late night informericals on real estate systems for the most part were nothing more than teaching people how to commit felonies. I don't seem to see many of them anymore. Not implying you are doing that, but it definitely made me wary of real estate gurus..
