Research SEO and try to make it one of your obsessions. Look into the techniques of Kyle Roof. Build a website around one of your existing special interests and using your SEO techniques get it ranking on Google. Then either monetise this website through paid advertising, or use it as a showcase of your skills and try to find SEO work. This is normally performed at home and alone.
Alternatively if you can face direction and instructions, become a virtual assistant for someone elses web based work which from what I can tell involves either data use or research so may be suitable. Unfortunately this is often performed overseas in low wage economies so may not be the best rate.
