$x,xxx
1,300 searches in the UK with a $18.90 CPC, it is estimated that with the average bid of $18.90 targeting the UK that one would get 6-8 clicks a day. That is around $58-$70 a day in cost.
So, you should contact the companies bidding on these keywords, like, "Hey, you guys are spending $1,700+ a month bidding on this keyword, why don't you guys buy this exact match domain from me for $x,xxx that would help you rank higher for this keyword." etc., etc. etc..... Any company with sense would buy it. Good luck.
