Wordpress Site with membership area and data processing

I need a wordpress website with member area and additional requirements that can be achieved with available plugins. oh, and i need visual composer. Wordpress website based on a given [login to view URL] to be set up including SEO optimization (like metas, alt tags and stuff, im NOT asking for optimizing copy text and headlines). all graphics and copy from me. 1. B2B part - sales page, product feature, benefits, contact, you name it (there is only ONE product) 2. B2B part - the same as above (content is more or less the same except some pictures and text) 3. Functionality Rather than giving you a list, i tell you the process and you get the picture yourself... Lets say the business idea is like that (what follows now won't make sense… its just to give you an idea about the process): A. Customer goes to our clients/shop and says: "I would like you to print my name on an A4 sheet together with 2 lines of text followed by an individual code, all in different sizes (sizes are predefined only once by me)." B. Our client registers with our website (if he hasn't done already), enters the customers name and email, enters his paypal adress and presses the "Buy"-button and we get our money, our client an invoice per mail, ..., the usual stuff. C. A PDF (based on a pdf template -made by me- with placeholders for the customer name and the individual code) is generated (theres a gravity forms plugin for that) and sent automatically to our client for him to print out. There is also an email sent automatically to the customer with his own login credentials (created automatically by the wp system, user name based on the mail address our client entered earlier and password = individual code from above). D. The customer logs into his member area, has to change his password and enters his address and contact details. Note: The customer still needs to be identified by the individual code from the system, because… E. ...if someone visits "[login to view URL]" he can enter his name and contact details and the matching customer automatically receives an email with this data. F. there should be an affiliate system (external, plugin based, whatever). lets say we have an existing client. He promotes our product to another potential client by sending him an affiliate link. new customer registers and everytime he orders our product, a certain amount is sent to the affiliate by paypal. Hope thats all and i didn't miss anything… I need an "alll in one" price and realization, so your price should include all costs incl. those for eventual plugins or monthly costs for external services. Please list them separately in your offer. Thanks in advance for your interest! ;-)
