Content seo editing and submission to CMS website

I have 57 pages of content of approximately 250 words per page that needs to be edited and submitted to a Joomla CMS website. For people who do not know Joomla CMS, it is very easy to use almost like MS Word to write and edit an article, so please don't worry about not being able to use it OK. The content is very well written, but I would like it to read better and it is important the grammar and spelling is perfect as it is a transcription/typing company website. The content also needs to have seo relevant words italicized, underlined and set as bold where appropriate and relevant keywords at the beginning and end of the content pages. I would like a quote for slight revision/editing of the content, as it only needs a little editing along with the seo element (relevant keywords italicized, underlined and set as bold where appropriate and relevant keywords at the beginning and end of the content pages), and another quote for rewriting all of the pages and the seo element (relevant words italicized, underlined and set as bold where appropriate and relevant keywords at the beginning and end of the content pages). If this goes well I would also like 500 word articles on a myriad of different subjects to be written on an ongoing basis and content written for a selection of other websites of differing subject. Thanks
