Developers & Designers need for an app

Hello, I've an idea for an application. In brief, the app will have two types of users - Service Providers and Consumers. The service providers will arrange transportation andd accomodation facilities as per the request of consumers when those consumers arrive at their city/location. So, service providers will be like an organizers for consumers. Ping me on [Removed by Freelancer.com Admin] I will discuss my idea with you in detail. I'm a data scientist so I can't handle all the tasks needed to build this. This is a NO PAY job. All the revenue generated from this app will be divided equally amongst the team members. I'm planning to launch it in January end or may be earlier, if possible. I need : 1. Front end (Preferably AngularJS) 2. Back end developers (Preferably Java/Scala) 3. Database (NoSQL) 4. Spark developer 5. Android developer 6. iOS developer 7. Marketing 8. Content writer 9. Any creative enthusiast to who would like to share his views/ideas and would like to be a part of it. The above may not be an exhaustive list. So, if you think you've got some skills that will help us in any way, you're most welcomed. Thanks.
