Create or install a few magento modules magento 1.9 -- 2

I need a plugin where standard product prices are not visible. for unconfirmed and not logged in users. These are only visible to logged-in, registered and 'approved' customers. so there are 4+ customer groups Customer status, the customer status (new) customers "New" The administrator may, if a new customer registers himself approve the customer and assign it to a customer group which may see prices. (Multiple groups possible due to different rates per customer group) The customer receives an automated email with the login information and the info that he is a confirmed user. Customer group prices, prices can be set per product per customer group. So each product has a price per customer group. Not confirmed users can also not (pre) order products.
