Birthday Reminder Service web App

Hi, I'm developing a service that will mail users a monthly set of birthday cards, along with a printed calendar filled with the birthdays of their friends, family and coworkers. What I need developed is the service that allows users to input their information, the birthday data, and to connect it with two existing services: Moon Clerk ([login to view URL]) and MailChimp ([login to view URL]). This may be through their APIs, depending on your level of experience. Any assistance you can provide in your pitch in making this workflow as seamless as possible will be greatly appreciated.  The user decides how they want to input the birthdays of their friends and family. They should have the option to pull it automatically from their Facebook account, from their Google+ account, and/or they can input birthdays manually. Their information is stored into a database, and sortable by month. I then need access to be able to print out each contact's upcoming month, with the birthday data (First Name Last Name Age (if given)) in the day of the calendar.  For each user, they should have a profile system on the site where they can manage the inputted data, and preview their upcoming calendars. If this would be easiest to set up with Wordpress, or a similar system, let me know. Thanks very much. I need someone who fully understands the task being asked.  Good with web development, integration, familiarity with Google and Facebook integration, Wordpress, MoonClerk or other ecommerce services. Experience with parallax is a plus, but not necessary for this specific task.
