Actually this is not a bad idea. Every assemble line has a minimum quantity, normally about 3k to 5k as an absolute minimum. Since I don't have a solid PO or deposit, using pre-order funds to order components and assembling line is the best option. Instead of setting up a pre-order account from stratch, why not using Indiegogo again? At least it has some security and a credibility in general. Thanks for the advice.
