If you enjoy writing articles and you are goid at it then maybe you can check on Contentgather. It accepts article for its article market and you can have your articles put up for sale. But if you prefer short burts then join a forum that pays for posting. One example is Forumcoin.
I don't think starting a blog will help the poster at this stage as the best thing needed is for understanding how the world of freelance writing works. Later, moving to higher grounds like having a blog can come up.
I think it's helpful to first know the niche area you want to write about. Parenting? Travel? Lifestyle? There are just so many different content types that it's easier to recommend if we know what kind of freelance writing you plan to do!
If you are just new to article writing why not start with forum posting then you can take it up from there,I think you will be better that way but if you still insist with article writing then you can try upwork and freelance .com and see how it goes.
