Need drupal 8 autonews blog website (from RSS)

I installed Drupal 8, Need news site 1. It will import RSS feeds to nodes (posts) A. Can assign each feed to specific category B. Under feed be word "Source" and link to original article 2. Can make custom change in each feed like: A. Replace HTML code B. Filter specific class and id if needed C. All photos be removed from the feed 3. Will make sure same article will not be uploaded more than once, even if same article appear in several feeds (i think it can be done by saving urls of the articles we published in special DB, so each new article be compared with them) 4. Need theme responsive and similar to my WordPress site (will send you link) 5. Make sure site use minimum resource as it will have millions of posts/nodes 6. Site Can handle 10 million nodes and more
