I’m a professional webmaster/marketing manager, with a lot of web design experience, though I wouldn’t claim to be a great designer. I’ll give you my blunt opinion, since you asked for an “honest critique”, which you may not like, but you may also consider that my experience might give me some insight.
The design is really old fashioned and amateurish. And also, without even looking at your source code, it’s screaming “Microsoft” to me. The title and banner are way too wide - the site becomes left/right scrolling at 800 x 600 - and they don’t really contribute anything to the design. In Firefox, two background images are broken at the top of the page.
The background makes the site look like a 1997 Geocities “here’s my CD collection” home page.
The font for the bullets on the left looks clunky. The copyright info doesn’t need to be at the top.
Way too many words on the front page. You don’t explain exactly what the product does until paragraph 4.
There’s a huge amount of blank space at the bottom of the page.
In short, in my opinion, and please don’t take this the wrong way, as I want you to succeed: it sucks.
My recommendations:
Don’t use a Microsoft product. There are lots of nice templates available on the web that you can download, and lots of free WYSIWYG software to drop the template into.
Stick to a fixed-width design, that’s 800 pixels or less. My personal preference these days is to have it centered, and then to fill in the blank space either side in larger screens with a soothing colour or a neutral gray. Maybe a 150px wide nav menu on the left, and the text on a white background filling the rest. Here’s a random example of that style, though that’s way beyond my abilities in quality.
Create a navigation menu on the left (where your bullet points are) but also put a contact link in a convenient location within the design, on every page.
Keep the front page pithy, with bullet points or links. Make sure you say what the product is immediately. Make sure that someone visiting the site for just 15 seconds will be able to recall what your service is. E.g. “Attorney Case Management is a program that allows a single attorney or small office to oversee an enormous caseload”. Break down your detail of the product over several pages, or make a linked FAQ page with a bulleted list of questions, and internal links that jumps to lower down the page.
Keep the fonts consistent, and keep highlight colors in tune with the design colors. Use a nicer font than Arial - Verdana or Tahoma.
Make a contact page, with an obscured email (or you’ll die of spam).
