Create a Wordpress Template

I want a website using API Aliexpress to display products on my online store by retrieving the images and description of the product Aliexpress, to show it on my online store at a price that I would decide. When someone buys the product Aliexpress on my website, the seller of the product on Aliexpress will automaticly receive the price amount of the product. For example, if I sell the products and $ 5on my website and on Aliexpress product costs $ 2, the seller automatically receive $ 2 to pay for the product and sent the product to the address that my client will choose, and I would keep the $ 3 in my Paypal account. My client does not know that product come from Aliexpress, he commanded by my site and the script I request, must send customers information and the product of the amount the seller to aliexpress, and I'll keep the rest of money.
