Fixies Ecommerce website with MLM

I need a ecommerce website with CMS (drupal, prestashop) that can be hosted on my go daddy account. I directories/code, image placeholders. I prefer a working demo of the program before agreeing to purchase. Long term position is available to maintain the program as we add additional functions, features. The main functioning areas needed are: 1) Website Management/Replication 2) New Member Creation/Sign-Up Page/Database 2) Back Office (Leader and Member/Members Only area)user profile 3) Forced Matrix (MLM)commission calculation. 4) Email/Auto-responder system 5) Contact Manager 6) Member Profile with unlimited custom fields and block replicator 7) Cart The website will be free with a small inventory of products to sell. For members we need to be able to manipulate compensation packages/comission structures. The most important function right now is to replicate the website with shopping cart and catalog function, a simple sign up form and track the sponsoring member and genealogy tracking. All custom fields, except what is on the initial sign up page need to populate on the newly replicated member’s website using the “sponsoring” member’s replicated website by using the sponsoring member’s username or ID to capture these field items. Each member then needs to be able to replace these “links” or information in the custom fields for their back office that are then replaced in the website as added or changed by the new member. I need to be able to had as many of these custom fields as necessary to be replicated on each member's website by the information that they put in their back office. The back office needs to be customizable by admin or the website designer in aesthetics to suit the look and feel of the entire website design. Directory names and file names need to be clearly labeled so that they may be accessed and changed by web admin.
