Ryan -
my honest (brutal) opinion - delete it.
Anything that starts out with "Dear Friend" isn't worth 2 cents of anything. 98% of all spam emails start out this way and you certainly don't want to be associated with these.
Also, you could spare yourself the entire written sales pitch by making a short video that includes excerpts of the eBook you're selling.
Also, what are you explaining in your work? Currency/Forex or the Stock Market. As volatile as the markets are these days, I'd rather make clear that you're talking about currency exchanges not "the street (market)".
The last thing you want is to have people think about disasters like AIG, BSG, etc.
Bottom line: Text - out. Video - In. Screenshots with voice over will help in addition to YOUR face being on screen. Unless you create traction via a believable message, you're just one of the eBookies.
