Well...I will start with this...
At the bottom of your sales page it reads:
Remeber Your Investment Is Secured With My 100% Iron-Clad Money Back Guarantee
The word "Remember" is missing something.
I would also offer another suggestion...
Give a copy of your ebook to three people for free in exchange for a testimonial of what they thought about it.
If you get only two testimonials this way...you can put those at the top of the page under the headline, to add credibility.
And one more piece of advice...
I do like your headline, but it needs strength. Also, use all red letters in the headline and remove the "all caps." I would replace the word "just" with simply if you leave the headline as is.
An example right off the top of my head, not following my normal process for determining headlines and only to be used as a guide for you (I usually write out about 200 headlines and pick the top 10):
"Who Else Wants To Totally Transform Their Presentation Skills From Zero To Hero In Just Eight Simple Steps?"
Use 20pt Tahoma, red color, and change the main text to 14pt Tahoma.
Enjoy
