Launch a professional and social networking app

I am looking to launch a professional and social networking app that will provide both professional and social networking opportunities to its users. The app will include key features such as a profile creation tool and a messaging system that will allow users to effectively communicate with each other. I also have specific design requirements for the app that I will explain in greater detail during the briefing meeting with the Freelancer. I am eager to learn more about the developers potential ideas to bring to the table and would love to have a discussion about creating a unique and user friendly app to further enhance the user experience.
