QUICK MONEY: need a react + php developer for page speed and seo

BUDGET IS A PLACEHOLDER AT THE MOMENT I have paid more than 105k+ USD to freelancers in last few months. I have worked with more than 130 developers here and currently working with 130 developers. I am looking for an expert in page speed improvisation for a particular page. I will need your proposal to give me how much you can improve and how much it would cost and time. If you have prior experience and can show previous work related to it and have it in your profile, you would be preferred
