- writing. plenty of places still paying for content.
- use software like tradestation or wealth-lab to build a workable trading system. trade from home.
- background checks. with rise in VC investment is also new needs for doing cheap background checks.
- penny auction arbitrage. there's a new startup in penny auctions every day. they start off unprofitable because not enough traffic. meaning, you can win cheap ipads for almost nothing and then sell on ebay.
- project management. people still need websites done. You can outsource to india using scriptlance or elance and do the project management from home.
- e-commerce. 1 idea: do a blog about living forever. when it starts to get traffic start selling a nutraceutical package on it.
- photography. do weddings cheap. you have to leave home but dont have to work as many days.
I'll think of more if people like these ideas.
