What work-at-home things are available that aren scams?
Sell stuff on Ebay can net you some decent money but you will need volume or quality things to make cash. You could supplement that with other type of web sales if you come up with a good idea. If you have special talents you can write articles, do photoshop retouching, proofread, etc. Above all stay away from ads that claim that you make $20,000/month at home.
Yep, stating the obvious, lots and lots of people would like a job that paid $100 a week without being too demanding to do around their other commitments. So basically you are going to have to find something special that most of those others can’t do. The rates for things most people can do will be very low. Unfortunately, even if you have computer skills, so do quite a lot of people seeking part-time work. You will need to build on a high level of skill, or an unusual skill.
I’m a guide for About.com in addition to my day job. Being a guide basically means I write articles, blog, send out a newsletter, monitor a forum, etc, about a specific topic. We’re paid by the pageview but for the first two years there’s a guarantee of a minimum of $725/mo while the site builds viewers. It’s maybe more work than you’re looking for–they say guides average 15-20 hrs a week, my site is new and I’m spending significantly more than that–but it’s more interesting and has more long-term potential than some data entry jobs. You can browse the list of available topics here. Alternately: I’ve seen Craigslist ads looking for at-home typists or transcribers. There are also ads for telecommuting bloggers, but you might need several of these jobs to get your desired pay.
