I'm an expert that deals exclusively with page speed optimization. I'm not an all around "wordpress guy" that does many but nothing too well, like most who bid on this kind of projects. I am a person focused exclusively on page speed optimization.
I only deliver ADVANCED optimizations, not medium ones. The market price for ADVANCED optimization is 250-500$. I can do it for under 100$. I guarantee that this will be an ADVANCED optimization (render blocking removed, plug-in prioritization, pjax, etc.), not a medium one. And this will take at least 2 - 3 days of hard work.
I am an expert in this specific field and own a company working exclusively in this specific field.
