Authority site stopped being indexed and new rankings stopped!

Hi, I am very good with WP but have been working on a problem for the last few weeks that I just can not seem to fix. I have an authority marketing site that is 3 years old and usually always ranks top of Google for my reviews and posts in minutes but recently it has stopped getting indexed. I am unsure if it was something that someone else has done or why Google have suddenly stopped indexing my posts. I have created new sitemaps, [login to view URL] file, tried deactivating plugins and a lot more... As my site does is not ranking for new posts my business is really suffering...that is why I think its time to get some help! One thing I thought it could be is this section - [login to view URL] My site is Https but that was done through my hosting at siteground using a redirect in my htaccess file. I have also noticed that I have multiple .htaccess files for this site...and I dont know if I need them or not! My site is [login to view URL] Please let me know if you can fix this issue and how much? Regards Marc
