Hello,
I can help your website load super fast. Take a minute to look at my profile and the awesome 5 star reviews.
To give an exact quote I need to dive into the coding structure of the website. Please provide me website url and the admin access so that I can look into it.
Few questions:
1) Do you have a cloudflare account
2) Are you using any CDN services MaxCDN, Stackpath, Keycdn, etc?
3) What score you want on you website.... Remember I can get you any score even 100/100 .. The amount of work increases as I go deep into it to resolve all issues to get a score of 100... As you know taking the last bit of juice from a lemon is difficult than first squeeze..
Let's get connected and see what we can do together :)
Warm Regards,
Sourav
