Texbrokers.com, so far a legitimate way for writters to work from home

So I have been checking into this online writing stuff and so far I have found it to be a bit difficult to make any real money.  Sure the work is there, it is just very low paying when you are starting out.  And you have to spend a lot of time looking for a match to what you are capable of writing, which is more time you could be making money.
I read about a site called www.textbroker.com on another site and decided to look into it.  The idea is simple, as you write they rate your writing.  Based on how well you write, the more or less you get paid per word.
When someone needs content written, they select how high they want the quality to be, the subject and how many words long it should be.  Then the available jobs are posted on the site and if your ranking is high enough you can view the posted job.  If you like the details, you select the job and you are given a certain amount of time to complete the project.  Most of what I have looked at are due within a day.
