Wordpress Site with premium template, having problems with speed web google test

Hello.

I’m trying to pass google web speed test with this template but something is slowing it down. https://developers.google.com/speed/pagespeed/insights/


Images customization is not all the problem

Too many scripts and CCS loads and too big files, no mobile friendly.

I would like to know if I can get help deleting some no needed code lines for my web as well as comments deleting.

I also want to know how to take this panels out. (images attach web1)

If you drop me an email to gmail(at)moskvayigit.com, I could offer you a fixed price for the job.
We could also work via Studio, if you’re interested in by contacting me via this link

Best,

Yigit
