A place for moms to connect
WAHM.com I hear offers some legit work from home opportunities (check out the forums). RedVision as well.
You can do something like Pampered Chef, Avon, Pink Zebra, Premeir Designs or Thirty One gifts. (http://www.directsalesaid.com/top-companies) I have alot of SAHM friends who supplement their income with these ventures. It offers them schedule flexibility many of their parties I have gone to they brought their children along...no need for daycare. One of my friends even used her earnings to work her way through Law school. The income can really pay!
If you are crafty, open up an Etsy account
Elance.com offers freelance work.
Or babysit for some of your working mom friends, that can earn you some extra cash as well. (I did this when I was a SAHM) or try to apply to a daycare center and have your children there with you as well.
Not sure if it's what you're looking for, but there is a position being advertised on the GainesvilleMoms.com homepage. Here is the link: http://jobview.monster.com/Advertising-Intern-Job-Gainesville-FL-11...
Also, when I was in school, I worked at a local preschool. The hours were very flexible, plus, I got a great discount for my daughter to attend the school. :-)
