If it's about passing coding tests, my advice is to ask money for that (like a wage of 42$/h). As you are skilled, you don't need to prove it (you already know you are). It's their problem if they don't trust themselves at evaluating people. Best companies I've worked for didn't ask me to pass tests. Customers I work with use to say "I want work with you (and not with someone else)" after talking a bit with me. Make that situation happened and you will feel better and earn more money.
