There's also typos in the slider.
EDIT: The whole site is littered with typos - you've even got your customers doing it, they spell surveys in their "testimonials" with an extra "r" just like you do ;o
From a website point of view the slider is too fast, can't really say much else except if it's aimed at UK people then why have dollars - and if it's aimed at US people they might get confused when they see it's a UK company.
From a user point of view there is not a cat in hells chance I'd sign up.
You're asking for quite a chunk of money, but there is no reason given at all as to why I'd want to pay you rather than some other company thats 90% cheaper.
What's in it for me?
You need some decent copy writing for it, ie a sales pitch.
IMHO
