Build an Online Store

I would like to built affiliates stores for Amazon, Lazada or Zalora that is sitting on single community version magento platform. Each affiliate store/stores will be pointed to a affiliate owner/owners. Aside on that, i would like to have online store as well where vendor can upload the product to his/her stores. User can register using openid, facebook, google, twitter and share the product upon checkout to their social media. Each registered customer must be tied to a customer referral. E.g. I introduce customer A and when A registered, it will be my child. Reward point system should be in level where it can be set up to 6 level. e.g. Buying customer - 5% Parent - 2% Parent's parent - 1% so on and so forth
