Odoo installation

We need an Odoo 14 proffesional to install this software on our Ubuntu 20.04 VPS server in a folder named CMS and on a different port than other apps existing on the server. We need installed a SAAS module witch will permit use Odoo with multiple companies and for each company we will have the posibility to allow acces to different modules. For example we need for transportation companies to have acceas to speciffic transportation modules, for construction companies to have acces to specific construction modules whitout see the other company specific modules, informations, user or documents.
