In reply to BURTON83:
Sponsership is an old chestnut, and understandably a lot of people are put off by it. I know you have said your attempt will be entirely self funded and the sposorship money will not go towards it, but you might have an uphill battle convincing people who don't know you. Also to the general public, Obergabelhorn means nothing
Why not just do it, take loads of photos, then do a seiries of illustrated lectures? Make them entry free, but emphasise that and at the end of each lecture tell them that it has been free but you are trying to raise money for the cancer charities, and if the audience has enjoyed it please please make a donation.
Making you lectures intersting so that your audiences enjoy them will be a far greater challenge than climbing the route.
I don't know you and I wouldn't sponsor you, on the other had if you were giving a lecture tour in my area, and I enjoyed your lecture I would happily donate afterwards to your charities.
