i have had a website development business under the domain name
mediamindset.com since 2002. i am retiring and am interested in selling that domain name and the website. The site is registered with all of the major search engines (including yahoo). can someone please email me at <<email snipped>> with an estimate of this domain's worth?

While this is a DOMAIN name appraisal only, it would be difficult to put a value on the website as well without knowing anything about it.

DOMAIN value alone will depend on traffic and backlinks you have pointing to the site.

I think you should try out selling in sitepoint market place/namepros/ auction sites which will increase chances to get potential buyers.
