Something To Fall Back On

I've been thinking of more ways to earn money while just staying at home taking care of my son. With our own stocks portfolio badly hurt and there's no tiny glimpse of hope for the economy to shape up anytime soon, a fall-back source of income is really welcome. I saw various small business opportunities online that are worth considering. Since I have a background in income tax preparation, I am looking at the possibility of doing tax services again. But I will need comprehensive training again to refresh myself and keep up with the latest updates in taxation.
