Not sure you really want to set up a company in Thailand. As a foreigner you get ripped. To start with, you need to register 2 million baht of capital (i.e. put nearly US$70,000 in a Thai bank) in order to get yourself a work permit so you can work at your own business. In addition, for each work permit you must also have 4 Thai nationals working for you, or at least shown on your company roster and registered for tax withholding. You also need a bunch of funny articles of incorporation that name 7 shareholders, a registered Thai accountant, and various other permits and fees that you don't want to do yourself so you pay an attorney. It all adds up to about another 200,000 baht. You might also end up blowing some money on a location since your biz must have an address that is for commercial purposes and you usually can't get away with using your home as your biz location.
