Looking for a top site value calculator site - in the top pages of google

Hey guys,

I am looking for an established site value calculator site in the top pages of google - Preferably the site would need to have good traffic and alexa rank etc.

The sites would need to be like these - if not them:

http://www.cubestat.com/
http://www.websiteoutlook.com/
http://www.urlappraisal.net/
http://www.webworth.info/
http://mysitecost.com/

I am very experienced in SEO and programming so would just need the site- but it must be a top site.

It does not specifically have to be a site value calculator - it could just analyse one's site like this for example: http://www.statshow.com/

I would be willing to pay from $500 to into the thousands - depending on the site obviously,

Please let me know via PM or through this thread,

Many Thanks.
