Starting on the side

Do you hate your job? My brother-in-law hates his job, and he´s asking me for advice on how to start his own business. The difficulty is that, my sister, his stay-at-home wife, is afraid he may jump too soon, and give up his job with health insurance, a 401k, and other assorted benefits. My solution? Go to a site like Bigstep.com, and set up a storefront for his prospective new business. That way, there´s minimal cost, minimal risk, and he can test his new business idea in his spare time, and maybe even generate some surprisingly good results, without having to make my sister nervous at all.
