Hello,
I have gone through your requirement and I can complete this within given timeline and cost.
You need product page and other pages of website to load faster. I have very good experience of page speed optimization on tools like gtmetrix, Google page speed.
I can share good suggestions like CDN implementation (max cdn or cloud front), set expires and cache control headers, browser caching of static content, resizing images, remove bad request url etc.
Please share further details with me.
Looking forward for working with you.
Thanks,
