Is it possible to retrieve WP site from clutches of old Web-designer?

Hi,
I have a client who had a previous designer/hosting arrangement and the designer didn’t pay their bills, thus the server was shut down, and the client has no access to their content/data. The site is/was ForeclosureCampus.com, and it was built on WordPress.org. However, ForeclosureCampus.com/wp-admin goes nowhere.

Apparently, they had about 100 hours of work put into gathering the content, so I am trying to conjure a way it could be retrieved, perhaps by FTP, or some cached data. Go Daddy was the hosting company, and the previous designer rented a server. When the account was terminated, for non-payment, the server is cleared within a few weeks, and any data that was there is no longer accessible.

I would appreciate any recommendations, or even ideas on what could be done to rebuild the site. I have asked the client how the content was transferred to the designer, for use on the WP platform, and haven’t heard back, but I would think email attachments, etc. would be a great starting point.

Thanks,
Steve
