Hi Nicole,
Firstly, I would suggest you go and make yourself a cup of tea/coffee and give yourself a couple of hours to just read, read and read. Anything "scammy" that is posted here is VERY quickly sussed out. Get a notebook and write down everything you think sounds good. Then when you have time, open a new email address (hotmail, gmail) and start signing up.
You will soon get a feel for what works for you and what doesn't.
I've got a blog post about the Top 10 things to do to earn extra cash - http://fromalditoharrods.com/top-10-ways-to-make-extra-money/
