To truly prep well (this would include making props, maps printed on 'parchment' and all that) and make sure you are up to date on all relevant rules, have good notes on 'what happened before' etc.) means you have at least as thrice as much time invested in prep as actual play.
My costs were based on an exchange rate of £1 = $1.5, rather than the current odd level. For campaign play, I assumed one hour of prep per hour of game time (I'll cover one-offs a bit later). I also assumed this was a side-venture rather than my main source of income, so I didn't include a 'risk factor', but did include something of a premium for cutting into my valuable leisure time.
Your prices scare me... but it would absolutely be your prerogative to charge whatever you thought the market could bear.
About one-offs: My assumption here is that the prep time for a one-shot would be significantly higher, since I'd do props, pre-gen characters, and all sorts of handouts (basically, I would supply everything that was needed to game, including books, pencils and dice). However, by the same token, the assumption would be that I would build up a 'bank' of a dozen or more pregenerated adventures suitable for repeated use. As such, much of this prep time would be considered an investment for later one-offs. (And, by the same token, I wouldn't be open to a group hiring me for two one-offs per month rather than the campaign play option... at least not without paying more. As indicated, the expanded prep has to be an investment to be worthwhile - without that I have to either cut it down or charge more.)

I think if you're going to charge you should have some type of credentials. Either won a major championship (two time Gencon Iron DM) or have made a significant contribution to the RPG world.
Ideally, we could really use some sort of really good ranking system for DMs, something covering not just rules-fu but also storytelling and table mastery elements. Alternatively, some sort of clearing house where customers can post reviews of DMs they have used in the past. Assuming five grades of DMs, I would then expect to reach at least the second-top grade before considering charging (and, in my arrogance, I would like to believe I am good enough to get there already).
However, restricting it to people who have won championships or people who have made a significant contribution not only vastly limits the field (and especially to those who can actually attend GenCon regularly), but especially the second criterion doesn't really give any great indication of actual skill - Jack Chick has made more contribution to RPGs than most people here, but I doubt he has any skill as a DM (I expect it would be
fascinating to find out, though).
