Sponsors!!!!!!!!!!

we're part of a small local riding group in southern cali. we are all in the marine corp too. the base we are stationed on is starting up a larger group that will consist of a couple hundred marines. diff types of bikes from street to dirt. once we get this larger group on its feet we want to look at some sort of "sponsor" with the local dealers and shops out here. nothing crazy but just maybe a discount if the group strictly buys misc gear from that store. my question is basiclly what is the best way to go about this without sounding like some punk thats tryin to get a hook up.
