What is our website for?

I discussed this with Peter today because I'm trying to get to grips with updating and improving it.
It's got lots of promotional stuff about services, but almost no useful information or links to resources for our clients.
So we started talking about adding it by having a 'useful stuff' section where we list top tips and link to the excellent ICT Hub KnowledgeBase.
Here's a site that seems to have got it right
ESP Projects
It's a not for profit ICT project in the north west [of England] - nice site - built in Joomla and with lots of handy hints on it.
Oh but on another note it has no rate card - which is another thing we need to sort out on our site....
