How can i get a business or organization to sponser money for an event?

Does anyone know any business an organizations i can get to give money donation for an event i'm hosting? an who would they be? also is there a car company that will donate a car to a poor family for free if i contact them on the family behalf?

Put together a proposal for the company(ies) you are intending on approaching for funding, provided it is a valid cause, most LARGE companies will do it over smaller ones (nice little tax deduction) as for the car, you may have to speak to an organization to accomplish that type of assistance.
