Happy to oblige. Ideally we could even find one of those rare gems....a company with both revenues and profits.
But potential scams, if that's what you're looking to avoid, aren't all this obvious....avoiding those that promote the use of magic catalysts should be our first screen. Then we would move to eliminate companies founded by people who rob banks and give the money back. Finally we would strike off the list of candidates any companies that use raw materials that cost more than they can charge for their finished product.
