Personally I think it's all good. I think there is huge potential in sports and organisational)scholarchips. Most clubs and groups needing sponsorship have no idea how to go about getting it and a bad request for support from large companies is a definite no no. You'll get it down to a fine art and be even more marketable. (You know they aways have a sponsorship request format they follow eh - just ask for it)
Go for it
