looks like you dont know what are you talking about
i know you used Google Keyword Tool, everyone who use this tool know that many of keyword search results are not accurate, 68 million on girl to girl is fucking joke, just check other tools and you will see that few k a month is max
let me guess, nobody is visiting this website right ? isnt this strange that keyword gets 68 million searches but there is no traffic straight to domain ? comee onee
so what about "girls-for-girls.com" or "girl-and-girl.com" its 68 + 68 million ! wow i just gave you 2 domains with 136 MILLION SEARCHES MONTHLY
for free !
lol
i see two possibilities here:
1) you're so naive that you really believe in all results that Google's tool is giving
but i doubt, so i think that:
2) you're looking for some poor naive guy who will buy this 68 million crap
but ok, i understand, business is business
