paid programming blog posts - articles and tips, corrections

I'm looking for skilled reliable developers who can write technical articles for my popular website. The same way as they would do on their own blog but I can pay for their posts. Our portal is quite popular and at first places on google so this is also opportunity to introduce yourself. Short note about your person and your skills will be at the end of each of your article also with a link to your own website/profile. I'm interested in topics: >>HTML5, SVG, CSS3<<, Joomla CMS (creating components/modules), Java, Spring, JSF, IceFaces, EJB, Hibernate, Javascript frameworks, jQuery, SEO tips, Liferay portal, etc. There is no exact topic - it should be what the person knows the best and would like to share with others. It should be interesting and easy to read. Looking for a long term co-operation at reasonable prices. First I'd like to start with small tips/articles to see potential of developer, then giving him more responsibility for longer articles. The content should be unique, not copied from somewhere else. After I pay for an article, I buy this article including copyright. Paypal is required. If you don't have time and you are involved heavily in other projects, DON'T BID. I won't accept excuses. Thank you for your understanding. Another thing what I'm looking for is some developer - native english speaker, preferably from US or UK, who can make corrections on existing posts by other users who are from other countries including me. If you are interested, please reply with overview of your recent work, topic you'd like to write about, CV and rate per 1000 words at which you would be able to create such content. Thank you!
