I am all for trying to find sustainable ways to finance these kind of projects. But in practice I think the way it's now makes it unlikely that you will get our money. For once, I can't find a price, and secondly, I get tired just thinking of the process of figuring out how to pay someone somewhere money.
I, and most developers in my professional circle, can do purchases through their respective cloud provider. Maybe you should check how easy it is for you to get it in as a product in e.g azure marketplace?
