Since December of 2008 we have a partnership with a company that creates the best flash made websites I have seen in the market.
They specialize in making sites for malls/universities/and other kind of similar businesses.
The way the websites are generated are based on the infrastructure of the company itself.
E.g if its a Mall/Shopping Center then the site will be based on the structure of it, while the user interactively goes around the shopping center and navigates, its a 3d virtual world on flash implemented to the website.
If you need something of the sort let me know by contacting me through the Contact US form or by using the form at Smoothosting, please send information on the business though so we can generate a quote. Also provide any ideas you fancy on the structure of the site.
