Ordershop without payment

I work as a sales representative for a designbrand. I need help to create a ordershop in shopify. The "order shop" has a function similar to e-Commerce, but for resellers to place their order of products from a Product range of Cult Design Sweden. I will provide you with a document that shows the Products that needs to be featured on the site. I want to create this function; Clients (resellers) select products from a gallery (as a normal webshop), but in the end of the process, instead of choosing "purchase" they choose "order" and after that, specify their company details and send the order to a specific person/email address. Important is that the receiver needs to see that the order came from my site and that the sender/client receive a auto-message and confirmation from the order with additional information. It´s between 100-150 products and I need the shop to be done asap. Looking forward hearing from you. Thank you!!
