Suppose I want to set up an area...

Well, to start with, you'd likely be in violation of a whole mess o' SEC regulations. I'm not a lawyer, but you certainly should be speaking to one before you go any further in your research. (The fact that you didn't mention the phrase "accredited investor" is a tip-off.)

That being said: I don't agree that "the process should be automated." It seems to me that the process would be infrequent enough, and specific enough each time, that any attempt at automation would have an absurdly low ROI.

In other words: there's a couple good reasons why you haven't found what you are looking for, and they have nothing to do with finding the right keywords.

Is stock exchange not automated for the most part? People can buy and sell their stocks with pretty much just the click of a button. That's essentially what I'm looking for.

[michael_dorfman]

Yes, the stock market is automated-- and highly regulated.

Of course, the stock market is limited to publicly traded stocks, and there are all kinds of regulations applying to the actions of the companies traded.

What if I just add a place for visitors to donate and in return for donations I offer an arbitrarily small percentage of the company that just so happens to be proportional to the donation amount? Those who donate will just have to take my word for it. :P

That's exactly the kind of thing the Securities Act of 1933 is trying to prevent.

Seriously, talk to a lawyer. Or, at the very least, start reading up on Securities Regulations on Wikipedia.
