Its HiFX which allow up to 2 years of 'fixing' an exchange rate. Give them a call and see if that can help you in your debt repayment plan for over there. Person you want is 'Christine Seargant'
Usually these type of places do these kinda deals when trying to buy properties abroad, but looks like from what Chrissy says that they also do other financial services too.
there's another company called 4 x money corporation, whose advert in the place in the sun magazine quotes the best exchange rate out of all the top 6 or so providers (inc hifx, travelex, moneycorp etc etc) check em out here
