SEO expert needed urgent

I am looking for SEO expert who can help to diagnose and fix the problems i have. You should have experience with penalties and recovery. I suspect my website is hit with some penalty or whatever it is where it start to lose organic keywords visibility, however i cant find out problem for this and i urgently need some help before its too late. I have seen some websites recover from this by just changing their URL keep same content and doing 301 redirect, however i tried it once it didnt help as i expected to be honest.. According to ahrefs im losing more and more keywords day after day on my site as you can see on the image: https://imgur.com/j2miRFs

Now on this image https://imgur.com/a/xLZh4 line that show organic keywords on ahrefs since middle of february is heading to bottom and if i not stop it soon ill be left in 1-2 months with no good keywords ranking or showing for any post at all..

Advises like check google analytics when traffic dropped or check search console dont help me much unless you expirienced this exact same thing and recovered and know what to do.. there are no technical errors on website according to all major seo checkup tools. Content is great and unique from native writers. I am ready to show WMT and anything you say through team viewer to analyse whatever you need.

Im ready to pay any price if you help me at least find out what is the problem and show me any proof.. without guessing and speculations.
