Replying to Shop Sponsorship Question

Ok, I just wanted to know how you find out if a shop will sponsor you? And how would you go about getting sposored by it, with likecontest results and a video like regular sponsors...and for people that are sponsored by shops...what do they do to help you and are there any specific things you gotta do for them to hold them as a sponsor? This really helps if anyone can anwser these for me. Thanks
