Wordpress migration for news website.

We have 9 WordPress news websites on the same server that have been compromised by malware. We need an experienced WordPress developer to recreate all 9 sites on a new hosting server using a new, clean theme, then safely migrate the existing content (posts, pages, images/media, categories, etc.) without transferring any infected files or malware. The goal is to have clean, secure versions of all 9 websites running on the new server. Rate is $200-$500
