Experience tells me your problem here is partially rooted in your sales copy and core message - it's too much about "we" and not enough about the visitor. Your site here leans too much towards how swell you think you are. Not much about what sort of instant gratification is in it for ME, the visitor. So your copy is not so good.
The other part of the problem is that your site, when I look at it, I have no clue what you are about. Why should I investigate? what reward is there for me to figure out exactly what you do?
Most folks are gonna land on this page, take one look at it and think "what the heck is this?" and leave. You have to grab their attention in under 1 second.
You've mis-spelled "testimonials" too.
