Modernization of the portal integracjasensoryczna.info

We would like to modernize both visually and, above all, technically our portal integracjasensoryczna.info. Ultimately it should be an easy-to-use portal with easy-to-access articles, which are easy to read both on a desktop and on a phone. We would like, first of all, to transfer 1:1 all articles and reviews (with stars, etc.) while maintaining SEO principles so that we do not lose earned positions in google search.

We would like the portal to include the ability to add events and display a calendar

We would like the portal to include a map analogous to the one we already have: https://integracjasensoryczna.info/gabinety with at least the same functions with the possibility of adding points by registered users.

Retention: https://integracjasensoryczna.info/telewizjais, so the possibility of adding articles with videos where from the list you would be able to play the video without going into the article.

Key for us and most important is to add a new option in articles _> paywall.
