there are tons of ideas. I have done call center jobs from home. Like those commercials for "....it slices, it dices, it jullienne fries and cleans your windshield in one machine, and tightens your abs in five minutes...and if you call now we'll send you not one but two...." well, those compnaies sub out the call center order takers. If you have a computer, some time and a headset you are golden. Search at home call center jobs in google and there are a bunch. PM me if you want the name of the company i worked for. I don't do it anymore because my kids would always wake up during my shifts.
There's babysitting, housesitting, this neighborhood pays a pretty penny in the winter for ppl to come help them string their christmas lights! And to help take em down in Jan. Any kind of yard work is nice paying here. Pet sitting, etc etc. there's so many things. Temp work maybe??
