LearnMarketing - aged since 2001; regged in com/net/org/us/co.uk/co/ca/tv/com.au and probably more.
Learn-Marketing with hyphen is regged in a few extensions also, as are some similar terms like learningMarketing, howToDoMarketing, etc.
Marketing is huge. Learning how to market is also a huge teaching industry, lessons and classes everywhere both online and in the meatworld.
For reseller value I try to imagine what a domain would sell for in, for example, a Godaddy expiring names auction or a Sedo auction with domainers bidding - I think this would easily fetch $1.5K - 3K reseller value in a domain auction, possibly more.
End users abound and teaching marketing skills is a huge industry. Absolute bare minimum end user value IMO is $3.5K, but could realistically go high x,xxx or into xx,xxx.
