Unless your in Pattaya where its 27,000 and 12,500 ????
First up you quoted me without attaching my tag
Secondly at that stage the OP had not stated which office.
Turns out to be Koh Samui.
The prices I mentioned were general and included opening bank account.
The low ball prices you quoted are Pattaya which is nothing to do with Samui.
Nor is your post concerning Phuket.
