I'm not sure, but I really asked myself, why should some sponsor help us, for what reason? I mean even when they think, wow that's unique what they made... the thing is companies are thinking like what can this do for us? and I mean, it will not work out, when we don't get attention by tv or radio, where we can make with our project some commercial for them.
I think if we want really have some sponsor, than we have (how mentioned earlier) many many people and for the best from many countries, so we can go to TV or something like that, magazines, radio, something that can help us to get attention... and at first, show them what we planned to do, how many we are, from where the fans are and so on... When I see the TV program here in germany I really think it's easy to get their attention (beacause of the shows like goodbye germany and other stupid shows) but they work, so when we can get one tv channel, like we make an documentary from our journey and our project, something like that, it would be easier to get some offerts and sponsors, like ana or jal, because than they have the chance to make also commercial for themselfs... but when we only write them a long letter that we need their help and so on I don't think, it will work or am I only too pessimistic? Sorry, it were only my thoughts...
but I will have some more thoughts, what exactly we could do =)
