How can I(from India) earn a good money from Internet without any Investment/ Fee.? -

I am tired of trying many ways to earn money from Internet for a long time. I tried many ways but failed. Please help me I am a student so can t invest any money. (I am good at AutoCad amp; 3d Max designing for interior and exterior)________It doesn t matter what country you are in, internet job-opportunities are virtually all worthless. I have never heard of a legit one.
