Yes there is, but your grammar and style have to be top-notch. ESL writers are a dime a dozen. (Dime a dozen = cliche term, best to avoid when writing for clients

)
Keep in mind that professional writers earn .10 per word and more. In some cases, much more. There are sites where you can earn that, but again, you have to be a great writer.
Additionally, Google's recent Penguin update essentially mandates that webmasters stop spinning content. This may well usher in a golden age of sorts for content writers.

On another note, I've found that many webmasters who complain of not being able to find someone to write high quality content for them are not offering enough in compensation, especially given the Penguin update mentioned above.
Webmasters, it is important to understand that native-English writiers can go to Textbroker, iWriter and Textmaster and earn $20-$100 a day without the hassle associated with private clients.
In short, we don't need you if you're paying 1-1.5 cents per word. Those who can pass muster at Constant-Content will never even need to think of you.
A semi-professional writer may well work at the $5/500 level provided that they can write and edit the article quickly. This usually occurs when the client's subject matter overlaps with the writer's knowledge, resulting in a minimum of research.

Tips for OP: (which aren't based on your post above. I didn't critically analyze it)
1. Avoid fluff at all costs. Adding fluff to increase word-count is the worst thing you can do for your career. You'll quickly earn a bad reputation, and/or you'll have to deal with laborious rewrite requests.
2. Keep thesaurus.com open while you write...and use it.
3. Get an online grammar checker. It will only ever be a crutch but it will catch errors that slip by when you're fatigued. I recommend correctenglish.com and grammarly.com, in that order. Neither is cheap. Consider an online grammar checker an investment in your career.
4. Ask new clients to pay at least half up front. Should be self-explanatory, I hope. If they're not willing to deal, move on. Once you've worked with them a few times, drop this requirement. It's just good customer service.
5. Don't accept orders with tight turnaround times unless you are absolutely sure that you can meet the deadline. Repeat business is the name of the game and being late is a good way to anger a client. IMers are busy folks, and they need their content now, now now.
6. Don't rely on Textbroker, iWriter etc. Yes, you can make a decent daily sum there but they will hold you back in the long-run. I'd say $20 a day is the max you should try to suck out of them. They're content mills, and they don't respect writers. Working in that environment will dampen your spirits over time. Besides, loyal private clients are where you'll make the balance of your earnings.
7. If you're a native-English writer and have impeccable grammar skills, you should join Constant-Content.com. You get to name your own price and if you write in popular niches and/or get private clients you can make great money.
8. Don't work with anyone who disrespects you or your craft in any way. Period. Complete the work and then terminate the relationship. It's just not worth it.
9. Don't take on more work than you can handle in a 24 hour period. It's easy to do.
10. If you can get work published on large sites or Constant-Content, you're probably a good enough writer to take a swing at publishing on the Kindle platform. Most of what's up there is junk, so you would have a chance to stand out. If you have a great story to tell or an insight into business, finance, etc, you might even write up a proposal to the Kindle Singles division of the platform, which offers a great deal more exposure and profit.
11. Know thyself. Write what you know and don't stray too far from your comfort zone if your goal is to make money consistently. If you take on a bunch of jobs that require extensive research you may find yourself working for 3rd world wages when all is said and done. That's not to say you shouldn't branch out, but you shouldn't make it your focus, either.
