One-on-one reviews are tremendously valuable, and I suspect not only large companies would buy them for consulting rates. Consider a startup product on the finish line, which lacks polish because non of the makers is a professional designer. If they are like me, they do notice that the overall design is not professional/engaging/appealing enough, but are themselves not able to identify why exactly, and what to do about it. Thats where professional designers are sorely needed. Me in that situation would not hesitate to pay you, say $600 (in european circumstances) to sit with me for 4 hours interactively, you giving advice and me tweaking the css/svg (the harder stuff for homework), provided a) I am convinced you know you skills b) You are able to communicate effectively with a non-designer c) You could concentrate on the low hanging fruit: Limited effort which still improves my design significantly. It won't perfect, and doesn't have to be. Note that for all of these points you would have to gain my trust, which is in itself a lot of work. Without that, I might still give it a try, but I would only willing to pay you throwaway money. But gaining my trust doesn't have to be one-on-one though, a good blog or your tutorials could do.
