Dear,
Mr Hernandez
All of the type of business you suggested to start are very very good, and i am sure you will get a great benefit on any of them.But keep in mind don’t take any of these type of work from your country(Indonesia), because working locally will degrade your value, if you want to make your setup world class, then don’t do domestic work , take only internationl jobs from Developed countries.
