If you need to have someone else write the content for your site you will need to be quite careful in choosing your author. You need to find someone who is knowledgeable enough to write educated information about your topic. You don't want jibberish content that doesn't satisfy your readers.

Believe me, I have seen some real crap provided to clients as SEO content. Yikes! There are a lot of writers around if you need them. Google for "writers" "content" etc., etc. One good spot that I have utilized is Get a Freelancer.

Be careful when doing this. I do not want to see you wasting your money. Look for credentials on your prospective author. Don't expect it to be the cheapest one there. Many of the more inexpensive writers have an arsenal of already written content at their disposal, actually, we all have this at our disposal. Check out the Article Sites, those site which people submit articles to all the time in the hopes they will be published on other websites. Some of these writers will probably just submit one of those articles. Or, perhaps do a re-write of one and give it to you. Let's face it, time is money, but if you are going to pay good money for someone to take an article from Wikipedia, or an article site, and simply reword it, you need to consider what you are doing. You can do that yourself!

If you can see a sample all the better. Be aware that some of these people are foreign and are just not going to write in American English, or even in English for that matter. Nothing is worse than content written in broken English, or worse yet, not sensable or un-readable.
