Contact the airline of your choice in the UK TG BA etc, and pay for the ticket there. The airline will arrange to issue the ticket in Bkk, or they will f'wd it to the Bkk office. It will not be a problem.

You can book in Thailand(It will be a fair bit cheaper). The ticket can then be couriered or sent by secure post, to the address in Thailand.

They had a ticket sent to me on Samui with no problem and at no extra cost.

Alternatively, contact Charlie at http://www.travelconnecxion.com/
