Convert a Template to a Website

I bought a e-learning wordpress theme from Themeforest. I have also bought hosting and the domain name. It is an online learning tool. People register, and registering allows them to access content on the website. Provided they are still a paying member, they should still have access to the website. I want the theme to be installed exactly as it is on the themeforest website. I want the website to load quickly, preferably in less than 5 seconds. I want Strip and Paypal to work on it. I want subscriptions enabled, the theme enables you to do this, but I need you to get this working properly, so that a monthly payment comes out of the customers account every month they are a member. I can send you all of the files required and the log in details. If you find that something is wrong with my hosting service, I am more than happy to change this.
