Offering 1:1 office hours in return for charity donations

The link explains more - I'm raising money to fight cancer (the Leukemia and Lymphoma Society, http://www.lls.org/) and offering up 1:1 hangout office hours in return for charitable donations.

The office hours are primarily to focus on product questions or issues you might have, since I'm a fulltime PM and former startup founder, but I have a few other areas of expertise that I am happy to deploy in your direction if you wish (from teaching introductory programming to planning out Paleo meals for a month!).

Great idea. I may steal it. I do office hours 'for free' now, but this might add a nice charitable twist... Thanks.
