I am not sure if you received my email - I searched for you through Google. We can definitely work together on this. The cost need not be exorbitant, though if you want someone of my standard, it at least needs to match my salary - i.e be fair :) I would get this done for you quickly too in my spare time - why don't we work out a job rate as opposed to hourly rate, this way you can have control of your budget? While we are on that subject I could also create the English version for you?
You've got an established ltd company in Thailand, a quality, flowing translation that's a tad more expensive is sure to be worth the investment.
Warm Regards Saowapan
