The thing about sponsorships of things like barcamps and heck any other event is the fact that you negotiate what you give up for the money.
Here they are asking for EVERYTHING, and not saying exactly what they are going to give up, for the 'privilege' of having them stop by... Do I give you the names of all of my attendees? How about their names and email addresses so you can spam the hell out the my 'entrepreneurial community'.
And don't even get me started on the mealy-mouthed help you solve your 'biggest pain point'. Which one exactly? Every event has its on hard pain point, but for the most part its finding a good venue. Sponsors are easy, usually I have to tell a bunch that I don't want them anywhere near my event.
