I need a website that estimates a site's income, e.g. $3000/month.
Searching the usual domain-info and whois sites hasn't revealed anything yet.
I realize that any such site is probably going to be a SWAG based on traffic rankings and such, but if I can give certain individuals a single URL, and it says "X dollars", then it's gospel to them.
This is for sites that we don't own, so we won't be privy to hard numbers.
