A simple but elegant website

I will commission a graphically nice, but functionally simple company website with the function of selling 10 products, on-line payment.

1. Description of the company's operation / About us / Contact

2. Store - 10 items - with the function of the referral / affiliate program installed.

a. registration as a Sales Representative - "from the street", after registration - full access to his account, Sales Representative - will receive his individual reference number with a link, where:

b. each entry of each client will be recorded + each purchase made by the "recommended" client, + commission (15%) charged on the last day of each month

I am asking only for offers containing the price for the implementation of such a page and the date of its completion. Lack of this information will result in disregarding such an offer. This will save us each other's time. Offers on the basis of "we will agree" whether I am "inexpensive" - will not be taken into account.
