how to make extra cash?

Hey, does anyone have any ideas of things I can do to make extra money during my nights and weekends? I am not crazy about selling (and I am not good at it) or working the corner (LOL). Things are just really tight these days and I want to help better our situation. I have looked at alot of work at home things online but how to do I know what is real and legit? I have already done the Avon thing in the past and made no money (because I am not good at sales). D has been working alot of overtime and has a good freelance gig going but they will both be ending soon and I want to do my part. I have started to clip coupons again but I need to find other ways to cut back and bring in some more money. We do still want to be able to live just a little bit, I mean life can't all be about work. Any suggestions??
