I can not open your site
immediately improve
The site seemed to be operational for a short while. Could have been opened just to show people that is is working so they could sell it or the owners realised it would take a lot more time than they had.
With this kind of project there are a lot of fine details that would need to be evaluated before purchase. Unless you could review the code yourself it would be a high risk buy!
As the domain is already down it seems like they found someone. Anyone know if there is a site around looking to sell a similar concept?
