E Commerce website

We have an existing one year old live ecommerce project in wordpress which is very basic. But, due to wordpress limitations, we need to recreate the project with following specifications both on website and app: 1. Shift All User information from current website to new one. 2. Feature like refer a friend and earn store credits. 3. Integrating API of Payment Gateways, paytm and shipping partners. 4. integrating existing social media links with the website and feature of sharing products and offers on social media by any of the user. 5. There will be two major categories of products under which various sub categories would be existing: first category is further divided into two sub categories: one in which order can be cancelled and other in which order cannot be cancelled. In second category, the order can be cancelled, one or more products of single order can be returned or exchanged. 6. Testimonial section would be there. 7. after login, customer can view and reimburse store credits. 8. social media images with certain hashtags are eligible to be shared on website. 9. flash sales: deal and offers with timer facility 10. message sending option 11. COD option as well as gift wrap option, that will add certain cost to the product. 12. add money in your wallet directly, that will raise the store credit value. 13. sms gateway integration. 14. mail integration. * Both the features need to be involved in app as well as website these are some of the main features, a bit more may be added; that will be discussed at the time of discussion.
