Book Reviewers Club: A web platform to read and review our published books

We are a publishing house and would like to create a new platform; a reviewer club. This platform's main goal is to allow our readers to "request" free copies of our books in exchange for points, which they can later review on the same platform. For the version 1 of this project, we only require: - A sign up page - A page with all the books - A profile page for every book - User's profile (only with the books they have reviewed + their points) - Point system; Members receive points for leaving reviews. These points can be exchanged for free kindle or paperback books. The main goal of our members should be to earn more and more points (or Inkitt Credits, as we named them) Please check the specs/wireframes. Everything is in there already for Version 1. We will deliver the final design, which means we only need backend (we want to set up an integration with MySQL to track who requests what book) and frontend development. The platform needs to be built ONLY on Ruby on Rails, and have an integration with MySQL. Please send me a message with your estimated (rough; doesn't have to be exact) costs for this project after reviewing the specs, and [Removed for encouraging offsite communication which is against our Terms and Conditions.] Thank you!
