Proposing Letter for Sponsorship

Hello,

i am new to English Forum and wanted to know if anyone can help me do a Proposal letter for a sponsorship. I want to get sponsored by a Sporting company for my sport, which is Cricket

I want to get sponsored for cricket, not for the fees but for having their goods such as shirts, pants and bats etc. and diaplaying their stickers on it.

I seriously dont have any idea on how to start it or what should i include.

The person incharge said i should include:

Benefits to me

Benefits to the company etc......

ANY HELP WILL BE HELPFULLLLL
