Website Speed Improvement -- 3

I have a website for my small business that I am in the process of optimizing for discoverability online. In a recent site audit, it was uncovered that my site speed, particularly on mobile is poor. The website is in Squarespace.

The full report for the site can be accessed via attached images.

I am looking for someone to help improve the speed of my website, especially for mobile. I am hoping to complete the project by May. Please include examples of similar projects you have completed in the past.

I reposted this project because I didn't want to waste my time to look for proper developer, furthermore developers bided without looking at my attached images and description carefully.
Sorry about this.

Requirements:
1. Start bid with overall percentages of both mobile and desktop from attached images with squarespace. like "squarespace 79m 92d"
here m : mobile, d : desktop
So I can notice you saw my attached images.
2. List your previous works with squarespace.
3. List methods to enhance speed briefly, not in detail.

I hope to look for Squarespace expert.

If not above 3, I will ignore.
PLEASE DON'T WASTE MY TIME.
I HOPE TO LOOK FOR PROPER DEVELOPER ASAP.

Because I have some experiences with software development, I can notice who is proper.

If you are confident about this, please don't hesitate to bid.
Thank you very much.
