Are there legit Online jobs?!?!

I have been diligently searching for a legitimate online job for the past month and all I can ever find are scams.  I'm getting very frustrated by this given that I receive countless emails telling me I can make a fortune overnight. Now I know that this just isn't possible however I do believe there are real legitimate opportunities online working from home. my hope is that by posting my frustrations on line someone out there will read it and have some good suggestions. So please, anyone out there, if you have been in the same rut that I'm in and you found a way out for real, please help!!!!!
