All these paid per tweets are USA sites, are there any UK ones?

I was looking on how to get paid for tweeting, the problem is,when I do a search for this, they are all american sites offering this service, there does not seem to be any English UK ones, and since I am from London, joining a USA one wont be much use to me as when I put in my post code of course it wont accept a London one.

Is there any UK sites that do the same service? offering payments for tweets?
