hi,

see starting a business after doing engineering is totally different. you must known about the market demands, the most important and essential automobiles or any others parts for industry etc. automobiles used in vehicles, in manufacturing sectors and architectural, civil industry. there is huge range of products available. so its would take a long time to make a business. however if you have any other business plane in mind, first try to do a full time or part time job to accustomed with the industry. then you can collect fund or take loan to start your own business.
