Senior "fill in a computer related skill", able to create small businesses, struggle keeping them afloat for years and destroy them in less than 1 month by making bad business decisions.
I have given up working for a living and am only working on fun things. I don't contract for money anymore, so I may give advice, but unless your project is "interesting" I'm not going to work on it for you no matter how much you offer.
However, if you are Caltech, I will make an exception.
