Development of a portal based on a template + store elements

We need to make a portal based on the existing website with the style. System based on Wordpress + Woocommerce. Namely, we mainly care about:

- making a landing page, which will be superior and will display the common activities of the company (two sections + common menu items)

- execution of the second part of the website on the basis of the already existing Wordpress site (replacement of content, graphics, videos and adaptation to current requirements)

- an online store is implemented on the site, but it requires an analysis of the current situation and adapting it to our requirements (digital products only)

- a system of access to purchased digital products (such as ebooks or training videos) based on publigo or our own solution

- adding integration with Google calendar + login

- additional features to be agreed before signing the contract, when we will determine the details of the project

The general idea is to use the existing site and expand its functionality to two departments of the company + common elements.
