Build website for digital sales

I need someone to build me a one page sales website and so I can sell iptv and digital products.

Must know what payment gateway I need to use and make the website is a way it encourages customer to take action and buy the product.

Will need
-payment gateway
-link to quickbooks
-Automated emails sent to customers
-affiliate link system
- Automated cart recovery
- 1 click upsells to enter a raffle to win iPhones etc

I am thinking of using shoplazza but I am up for suggestions.
