What I've learnt is that it's for businesses to productize SME solutions unless they're dirt cheap or free, but getting hired as a consultant (who actually adds value) is always an option. It need not be done for compensation either initially - you just want to build trust with the folks, advise them, maybe sit with them and evaluate already existing technical solutions on the market (instead of building your own!).

If you're in the US, you could just set up an LLC if you find some potential customers through the above method, very straightforward. Or you could set up the equivalent of a sole proprietorship in Europe if you're based here.
