Copy contents of 200 pages public WIKI into Wordpress-site

Hi there, We need to build up a help-section, which will be based on Wordpress, ie. we will build the helpsection up in wordpress. We need to copy all content from another WIKI with approx 200 page (crawler says 179 pages), and into the help section. All the existing content is publicly available in an existing Mediawiki wiki, but since this is not our wiki, we cannot just export the content, and there for need this manual process. All the pages should be copied as clean text and set up in WP to make for clean, simple HTML-formatting (i.e , , etc.). It is important that all pages are cleanly formatted + the structure is correct. Ie. we need you to also go through all pages and verify that the implementation is correct.
