I am looking at the possibility of having a website where customers can go to my site, and build their own website, from a set of templates on my site, etc. where they can pick and choose the look, feel of it. Once built, they must have access to a control panel to access their site to make their own changes, etc.
Site must be easy to maneuver in, quick loading pages, etc, be easily searchable for keywords, etc.
If you have already designed something like this, please supply portfolio of finished sites.
