I do certainly not agree with the above appraisal :p as i am myself a .tv domainer
Searches on overture are 22262 for Female Escort
s. Overture doesn't differentiate between plural and singular forms, but wordtracker does. Take a look at
http://www.digitalpoint.com/tools/suggestion/?keywords=female+escort&country=us and you'll see that Female Escort searches are lower.
That aside it still is a good domain, not for the Overture search value but because it's easy to remember, two dictionary words, the domain COULD fit the extention as it is a good market for television commercials, and it has a good market value by itself because the female escort market is hot.
Undevelopped to the right person you could sell for low $X,XXX. Developped with targetted escort traffic you could go for high $X,XXX. For a domain reseller the price would not go higher then mid - high $XXX. If you wait it out untill the .TV TLD is saturated you could easelly double those figures.
I recently had an offer for Sexpartner.tv of low $ X,XXX but i didn't sell. I also own Sexpartners.tv and recieved offers in the mid $X,XXX range to give you an idea. These domains also are "in a way" targetted with escort if you see it big.
Hope this helps.
