3 old websites need speeding up. It needs an expert who will be able to handle any issues like plugins breaking. They have live chat, bookings and payments.
I want someone who can get good speed scores, keep the sites mobile friendly and tick Google's Core Web Vitals boxes.
The websites have a lot of pending updates, e.g. php and WordPress version and plugins.
I need someone experienced with good reviews. I have had questionable experiences with 3 services so far, so I am only looking for someone who is very good - no shortcuts, keep me updated, be professional with communication.
