If you were being serious they do have an "invest" button on their website. I'm sure they would rather give you stock/ set up a repayment plan than go out of business before starting. They are paying rent on a building in the meantime so they don't have time to wait for tiny donations.
I talked to them via FB they said the banks won't lend them a cent, no collateral. That's part of why they tried the stock but they haven't made a cent. I imagine they are getting scammed as well by those they've hired to run the stock.
