I'll make a small answer my friend. Actually it depends on what type of business you would like to have , but the other pain is there is a bond or a deposited money wherein it will be only returned after you pull out your business. The bigger is your investment , the bigger is the bond. If you are a foreigner , you can ask the department of immigration for the first step. Then department of finance and commerce. That's what I only knew my friend. I got this info from a friend who has a big contracting business here. Goodluck
