make a research on your targeted topic "PC Booster Software" and learn how your competitor do their business. you can make a comparative presentation, product information (your product), product review. I guess that will do it.
If you have the time and energy, write the article. Research it, SEO it and then proofread it too. If not, outsource it.
I would outsource an article from a site like affout.com or elance.com pay no more than 3-4 bucks per article of say 500 words cheap if you ask me.
If you need good content, hire a good writer. If you can skimp on the quality, there are plenty of decent article writers out there literally charging for coins, like what the guy above said.
If you know anything at all about your topic, its cheapest and easist to write two or three articles and then spin them yourself. Check the finished articles through copryscape to make sure they are original and BAM you've got content.
Hi, You must go for any content related site for good content and then re-write it as per your requirement.
