Hello shashank..

Thanks for contacting Careers360...

A sponsorship is basically any business (large or small) providing another person/organization with money and/or materials requested by the person/organization. Sponsors usually require that they get exposure, usually by having the person/organization have their company's image up so that many people will see it. 

How to seek sponsorship..

1.Identifying potential sponsors

2.Creating a sponsorship packet

3.Sending out packets

All the best:)
