WordPress Refresh complete overhaul

We have a WordPress website that is on our dedicated server we would like to do a refresh on, it has been about 3 years since we actually attended to it. Below is the website we want to have updated. [login to view URL] HTTP Change: http to https Change since our server has a SSl certificate (or best practice). CDN: We would like to have everything served on the cloudflare (or best practice) Theme Change: We have a new theme that is a newspaper style theme we would like to convert to and redirect the pages we have now to posts. The logic is that we are trying to deliver information in a fashion that is easily accessible for SEO/SEM purposes (or best practice). I have the theme if you need to view it and will supply a few PSD files on how we would like it to work. [login to view URL] AMP/Schema/Json/Microdata: We want the ability to have valid microdata for each post, i know there are plug in for this and we will go on your suggestion for ease and functionality. Verify the AMP pages that are listed below, they have been quadruple verified and approved inside GA and seem to be working but and advice would be appreciated. Redirects/301: We would like to have all the pages converted to posts and everything that needs to be redirected (or best practice) PHP: All php changes that may/will be need to make the theme fit our needs (or best practice) Html/css: All html/css changes that may/will be need to make the theme fit our needs (or best practice) SEO/SEM: We will need the site structured in a fashion that applies the SEO/SEM best practices to insure we do not lose our current SEO/SEM and guide u on what is the best practices now. We have both Google and Bing analytic's Keywords/Meta: We can supply the keywords and meta data you may need or you can find what keywords and meta will give us the best ranking we can get. Content: We will supply what ever content is needed for the project or we can guide you on what content we may need. Graphics: We will supply what ever content is needed for the project or we can guide you on what graphics we may need. Most of our content will be copyrighted and trademarked which we have rights to use. Additional: We have 20+ factory/manufacturers certifications for collision repair. We need to update the content on these pages since it is just copied and is probably hurting our SEO. I have content for those pages as well as graphics to each page. we also have. These pages will be the anchor for sub pages that are built out and then redirected to that specific page for the sole purpose of SEO/SEM. We want your input on the SEO and if this is done in the best practices. We have the rights and are approved for all Volkswagen, if you need this but the domain has the association with it. Non of the other manufacturers require this, only VW. Summery: We are a factory certified collision repair facility and I have not been able to keep up on the website since we have acquired several other business and will be starting a marketing company. We are looking for person/company that we can work with on other projects that we may have.
