I get that you are young and still dreaming big but as I see it, this crowd funding plan isn't going to pan out and you really only have two realistic options...
a) Work hard and save up to fund this yourself. Morally dubvious occupations like banking or doing "something" in the city may expedite things.
or
b) Work hard at becoming a mountain guide and have rich people pay you to come along on these sort of trips.
Either way, hard work is involved and your dream will require to be very robust to survive it.
