so you are trying to collect over 150K ped, buy a full shadow or another uber item and then give that away in an event?
Very strange idea and very doubtfull you'll find enough ppl that just gonna give away that much money.
And next to that there the 'trust' issue, that you won't 'run' with 150K ped (=15K us$) once you've collected it.
Don't wanne burst your bubble and your intentions are probably good, but I'm afraid it won't work.
