Here's an idea, I thought of this just. Dead simple way to get articles written for you and also paid for your trouble. Put an ad on C*L for freelance articles writers. In your replies to the recipient, tell them because of the demand for the job ask them to write an article of 400/500 words on your chosen topic. Give them half a dozen topics to choose from ( all the topics related to your websites etc. of course). When you have your articles, send them a CPA offer for a freelance writer telling them, how good their articles are but unfortunately they were unsuccessful this time. Rinse and repeat. I did try using the search engine in here but as we all know, it's not up to scratch, so if it's been posted before, sorry. I know it's basic but it could work for you.
