be fully aware of the jobs that are restricted for foreigners to do as there are lots construction related. Basically you can supervise, but not work, in most of the trades. Your attorney costs can vary widely depending on what kind of business structure you use. Siam-legal is very good, and will answer lots of your questions in your phone call with them. Call them Monday. Setting up a simple business will involve hiring at least 4 Thai workers for each work permit. You'll need at least bt4million in registered capital to get your business license. You'll have about bt5000-bt10,000 in incidental monthly costs also.
