We have created a very large site over a very long time period. Its thousands of pages of handcrafted code built carefully and slowly.

However its already legacy before we even launch with much of the design being inline css and in table structure.

The site's design is rather messy in places, but it works fine even if looks a bit old hat.

However upgrading the site to look really smooth and nice for our launch is becoming a real headache with all this legacy code throughout the site.

Has anyone good any good solid advice on what we can do inexpensively. We have nothing really left after our long build program but we do need help getting this over the line for launch.

Thanks in advance.
