Best way to teach basic SEO?

[YahooDeana]

I taught myself SEO and want to help others understand and utilize it affordably. I am considering offering a short class (60 - 90 minutes) over a lunch hour to explain basic rules for folks to do themselves or have their website designer do it.
Since I don't work for a big SEO company (many of whom charge exhorbitant fees), do you think people would be willing to pay $50 ($10 would include lunch at local restaurant - places that have conference type rooms) to hear my lecture? I'm a nobody but I figure many would be willing to spend that over $1,500 or much more many pay to a company instead.
