Look, how about you make a thread where people could buy them directly and make IRL tests, potentials investors will hard a hard copy and they can back you up.
They will pay for the production and shipping, you will not have to spend / waste money.
i am not asking any investors until i am surely ready, i don't want investors loathed the time. plus designing the hologram and paper arts are gonna be consuming major amount of memory spaces and the artwork skills. i don't have a proper PC that can support 2~3 GBs of data in an image that will be used on the hologram design. right now this is but a dream yet i don't wanna ask any investors as told because i am not that reliable by evidence. i can create a preview but i don't sure how many people is gripping on.
fact: with all the required funds to begin the production, it is a $10.000 question.
btw i threw up the poll and let's see how many possible buyers i can get.
