Where to get sponsorship from.

Hey everyone,
I've just completed my 3rd yr in B.Tech and have decided to make a humanoid as a 4th year project and thus for that I need some help from you people, i.e I need to know some people or organisations in India which can sponsor for the project.
It is very important a thing for me as without sponsors the project is very expensive to be completed.
Please reply....
Please do help me.
