This plan sounds like it rests on the classic answer to how to make a million: "first, get a million page views"
I have those, now tell me what to do next :)
"Beware of people giving you advice that they themselves do not follow".
I figure if you tell people how to go and make a million you had better made a few of those yourself.
You can't allow that to happen, if you do you fail at the game.
You have to study all submitted options and pick the best according to all variables involved, time included.
If you get enough publicity perhaps Mercedes will give you a car for half the price so you can sell it quick, going from 50k to 100k in days. Or any other sponsors, Rolex may help you jump from 5K to 10K. Harley-Davidson from 10K to 20k, and so on.
Free publicity for the seller and for the buyer if they choose so.
Luck may be on your side...
