Recurring PayPal payments in Ruby website

Please reply only AFTER reading the project through! The client for this project works with annual memberships, with a start and end date. All member information, including these dates, is stored in a MongoDB database. The members interact with the website built in Ruby. So the starting point is an existing website with Paypal payments working for years (Ruby+MongoDB ). We now want to make recurring payments available to our members. We believe this should be simple for someone with serious Paypal API experience. Members come from different countries. Each country has an agent to deal with the members from that country. In some countries, the agent receives the payment of the members directly through PayPal. In others, the money goes to the company's PayPal account. In summary, There are several Paypal accounts used (depending on the country) and we need it to continue that way. Members pay when they subscribe and when they renew. The period for subscription can vary as can the amount and currency, but most members choose a 1-year subscription. The goal of this project is to allow members to pay recurringly. This means that a new user or a renewing user should be shown a checkbox that allows them to choose to be billed again after the same period for the same amount. If they initial subscription is of 70€ for 1 year, then after 1 year they would pay 70€ again and their membership would be extended for 1 more year. Information that a recurring payment will occur in the future needs to be stored in our database (indicating: amount, currency, and date the amount will be charged). This project will have 2 phases and 2 milestones: Milestone 1 - Project working on staging server 1.1 - We give you access to the code on Github, the database and all you request as necessary for project completion. We authorize your keys for our staging server. 1.2 - You develop the necessary code and make sure you have set up automated tests for it. 1.3 - You deploy the code to our staging server 1.4 - We test it for renewing an expired user. For this, we will create a 1-day membership plan so that we can see if the credit card provided is billed on day 1 and then recurringly on day 2. Milestone 2 - Project working on production server 2.1 - We authorize your keys for our production server 2.2 - You deploy the code to our production server 2.3 - We test it for renewing an expired user and also for a new member signing up. More information can be provided and I am available to answer any queries. If you have read this far, please start your offer with "If am awarded this 2 phases project I will complete it in ... days" (indicate the duration you think appropriate). This way I will know you have read it. Please note the code delivered MUST be readable and well documented. By the end of this project, it should be fully functional, tested thoroughly and available to the public on the production server. We are looking forward to your bid!
