Need WordPress Admin Help

I need help with posting articles, and modifying text on WordPress CMS pages. You must be good at formatting content in both CMS Pages and Articles. The Wordpress instances will be designed already and ready for deployment with the exception of new content on the CMS Pages. Plus you need to be able to post articles with good text formatting and picture placement. I plan on paying on a per project basis - maybe based on word count. Please indicate what your bid is based on.
