As far as I can see get your social network website running in the time it takes to make coffee (adapted from one of the sub-pages) is your core value proposition, and it should be in big letters on the home page instead of generic phrases like "leap-frog your competition and be a leader, not a follower" and sentences listing technologies.

Much of your text reads like it was written for search engines rather than humans to read, and your screenshots and examples could be a lot more attractive.

Looking at the price points you're looking to charge, paying a professional designer and copywriter would be worth the money here, assuming the end product is fit for purpose.
