Convert a Template to a Website

It's a shopify shop that sells jeep parts. The account and store is set, custom domain is linked. I have no time to finish it and need someone to do the following: 1- finalize all needed tweaks to ensure site is fully operational including the setup of the payment gateway (for GCC countries and based in UAE) 2- finalize the Facebook shop app which is already installed 3- optimize the theme. 4- receive my selling text, images and detailed for each product and populate these products to show online to start selling ( we have max 100 products)
