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


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
