Find someone in the UK you can trust and send them the approximate amount on a dollar cheque. They can pay the cheque into their account for a, usualy small, fee. They can then pay your UK suppliers from their account. It can take up to 20 working days for it to clear but in my experience it rarely takes more than 3 or 4.

It is a bit of guesswork due to the fluctuating exchange rates and you may end up sending to much or too little but what kind of amounts are we talking? Your bigger problem at the moment is the strong pound - Don't get much for your $ I'm afraid:-( If you do not have any trustworthy contacts in the UK (How about one of your suppliers?) I am happy to do it - Can you trust me enough?
