Mail forwarding

I would like an address - anywhere in the world - where i can have up to 10 letters sent in the next year. You will need to forward the letters to an address in the UK by the fastest method within 3 days of receipt. The letters must be posted so that no signature is required on receipt in the UK, though an electronic proof of postage is welcomed. The letters will likely weigh no more than 200g each and will only contain printed papers - A4 size. Excess postage costs for items over 200g will be reimbursed on a case by case basis.
