Ecommerce to order printed Instagram photos (joomla)

I want a website where the user can select photos from Instagram or from the computer and order products using this photos.

The website will be just like this one: http://www.socialprintstudio.com/products/

Basically what I need is this system working using Joomla. I need the shopping online, the Instagram authorization so the user can select the pictures on the website and the checkout system.

Just do the step to order using the website above to know what we want.

We dont need only the design of the system. The layout of the website we will do here with our designer.

Must be joomla 3.X above.

After the system is ready we need to change the language of the system to portuguese, once this website will be use in Brazil. Once is ready we provide the translation and the developer only need to change the text.

The other static pages of the website such as, about the company, etc will be made here after is done. what we need is this system working. (order photos from the user instagram or from the computer just like this website http://www.socialprintstudio.com/products/)

In the shopping online we will need to be able to create and give discount coupons)

Social login using Facebook

We preferably want a shopping online system using Virtuemart os Mijoshop but we are able to hear other options once the update of the products and prices is easy for us after the job is done.
