I need an at-home computer job. Any help?

I used to be a secretary (25 years). I had to quit because I have tremors (shakes). I can still do computer work of just about any kind but I cannot take phone messages. Now I babysit my 1 year old niece half days but it is not enought for me. I would love to do something at home on the computer - any suggestions? or any other kind of work at home?
