Hi Jim
Basically we are open to sponsorship, and we haven't really defined levels though the maximum we are looking for is $250.
Obviously the level of sponsorship will affect positioning on the site and also probably exposure on stuff like t-shirts (which we are looking into). The sponsorship would mean that you would be listed on the site, and your logo would be present on materials that surround the event. However, its doesn't buy you a speaking slot since that is counter the nature of the barcamp.
If you are interested please do drop us a line - also we will be providing a mechanism to register interest once the site is up.
Cheers
P
