Cost of developing 1 hour of elearning

I'm looking for someone with real-world boutique training company experience, to throw out some ball park figures on what their compnanies are charging small to medium size businesses for a 1 hour medium-complexity e-learning course built with Articulate Presenter, from the client's PPT deck.

Basically, I need a range. Can someone provide a price-range that works for clients in that market (small to medium size) that they have found from experience, just works. I would imagine that someone could say "don't settle for anything less than $2000 (insert real amount here) above your time and materials....but we price these courses out at no more than $15,000 (insert real amount here) per hour of seat time, because we have found that beyond that, we exceed what clients are willing to invest in the training project."

I understand the work-effort calculators. That is not exactly what I am looking for here. I am asking what the fair market price is.

Thanks,

Shane
