I think what you have to remember here is that design is very much subjective. As long as it converts at a level you are happy with then fine.
I have the same issue as Matt whilst using Firefox that it cuts off the images so thats something that needs to be looked at. For me there isn't really any brand behind the site, nothing that identifies it as you. It is uncluttered but equally I think it borders on being plain.
When I see someone saying they are a microsoft professional I expect to see the logos etc that go with it. It gives you credibility so any other memberships or qualifications I would be making a point of showcasing them.
I dont want to just pan the site but I would say I'd want to do more. I would have thought Wordpress would have been a decent platform for this type of site and there's loads of themes etc that are hugely customisable. By the way this is only my opinion and many may disagree with me
Logo's and content are on their way (copywriters job).
The error message: it does appear to be intermittent (I have seen it but when I go in this evening there is nothing through either Firefox or Safari). I think the problem is at haloscan's end as their site seems to be going up and down at the moment.
Liked the uncluttered appearance of the website - which to me always shows professionalism.
Didn't like the colour scheme very much but then again I guess you might be a Hibee!
Only other comment I would make, and this goes for most websites - is it possible to fit the whole page on to one screen, therefore avoiding the reader having to scroll, or worse miss important information.
