Hello how are you? I have great experience with optimizing websites and can speed up the loading of your using all recommended techniques (gzip, leverage browser cache, minify javascript, html and css and more) I will also set up a Free CDN, which accelerates and secures your website around the world (Cloudflare).
If we can access the SSH from your computer, I can further improve performance by using the MOD_PAGESPEED that will integrate to your WHM, this optimizes the whole site in General and the score in google will go up even more.
I am at your disposal and can start immediately
Best Regards,
Jonatas
