Any tips for noob getting my feet wet in the freelance writing game?

I've started writing at some up front pay sites like textbroker, contentauthority, and the like. I have also done some stuff for really low pay at bid markets like MechanicalTurk and Odesk. What I really want to get into is some residual income stuff and try to make a decent income each month. I'm a mother of 2 in undergrad,trying to get into med school someday, and if you have no trust fund you really have to find interesting ways to take care of everyday expenses. Personally, I'm just not a real estate/property management kind of girl, and I'm a really good writer (excuse me while I toot my own horn--TOOT TOOT--thanks), so if there are any pointers you could give someone who is trying to figure it all out that would be awesome. Thanks.
