So it really is that simple...just rewrite this site using the technologies above. The only catch is that I would like it to be well designed and implemented to be clear and flexible. Though I'm not a good frontend developer, I am a very experienced developer and I know good code from sloppy code. I would like this to be very tight and clean so if we choose to modify it later, it will not have hardcoded pixel references everywhere that make it brittle and unwieldy. We are willing to pay a little extra for this quality.
The core requirement is quite straightforward (replicate the current site with different technologies) so the key here is going to be the quality of the implementation. Here are some additional guidelines for coding standards.
* genuine and efficient use of CSS
* abstracted hardcoded settings (like any fixed pixel settings)
* clean, formatted HTML (no Microsoft Front Page generated mess)
The one possible complication here is that I do not know what state the images are in for the current site and so there may be some image doctoring required.
