You have misspelled, "Management", in the same line as your other mistake. Spelling mistakes are something clients obviously look very down upon. Makes you look like you're either too lazy, or incompetent to spell or even correct your spelling.
EDIT: You also misspelled "Wikipedia" twice.
Like akitchin mentioned, you should be using more real estate. Why not? I agree with your statement, "Statistics demand I have 15 seconds to get your attention or you will lose interest and move on.", but that doesn't mean that if they're interested they won't come back and want to check out the rest of your site. I would suggest looking at some other freelance sites to see what content they have to offer.
Get rid of the binary background, looks to 90ish and it's a distraction.
Overall it looks like you were too lazy to include any more information and the site was made within a 5 hour span. It has potential but needs some work.
