Scheduling Web Application

Please note a freelancer has already done 50% of this application, but has unfortunately abandoned it. Part of this engagement is to evaluate whether the application can be continued or started again. Project Brief Need a relatively simple Angular/Node or Meteor JS application with the following features: 1. Integration with a JS Calendar to enable appointments/scheduling 2. CRUD interfaces for Customer, User and Appointment Data 3. I strongly prefer Material Design UIs 4. Integration with an SMS provider such as Twilio to push appointment notifications to customers AND acknowledge SMS confirmations from customers (marking appointments as confirmed or not in a calendar based on the SMS notification) 5. Basic user/role management and registrations I have captured wireframes, boilerplate and a trello board full of requirements and will show them to the applicant who presents the least canned message/interest. So a lot of the planning and requirements gathering has been one. Just need someone proficient in Meteor/Node/Angular to wrap this up. There is also a somewhat working version of this lacking the SMS integration and calendar features that is available.
