Hi,
I wanted to message you regarding your project (Optimizing the website (Scripts, Database queries and Server).
I just completed a project like this:
https://www.freelancer.com/projects/php/Google-pagespeed-need-some-assistance/
With the result 65/100 to 97/100.
However, I must tell you that these scores can vary based on lots of factors such as: what kind of a web site this is (for instance WP, Weebly, Wix or Magento), the location of the server your site is being hosted by, the type of server (shared hosting, VPS etc).
Please contact me as I am ready to do this right away. You do not have to reward me the project. I can first show the results, if you are happy then you can reward me the project.
I look forward to hearing from you.
Thank you.
