Professional Social Networking Android App

I require a bespoke social networking Android app predominantly targeted towards working professionals. This application must include some key productivity features to help professionals manage their time and schedules efficiently: All the relevant information to what exactly I need is given in the attached word file. PLEASE READ THE ATTACHED FILE COMPLETELY TO UNDERSTAND THE FUNCTIONALITY AND OBJECTIVE OF THIS APP. I am new to app developments, thus may require some education on its development path. - Information exchange, buying/selling: Users should be able to share info, trade items, or even provide hiring opportunities. Expertise in e-commerce style features and secure data handling is therefore essential. Given the aim of the app is to cater to the needs of professionals, it would be highly beneficial if you have previous experience developing similar apps. Knowledge of UX/UI for a professional audience would also be advantageous. Thank you for considering my project, and I look forward to seeing your proposals.
