An app where users can book anything - barber, restaurant table,

I am in search of a skilled developer to create an app where users can book anything – barbers, restaurant tables, etc. All types of booking systems, such as calendar-based and time-slot based, are acceptable for this project. The target platform needs to be both iOS and Android. Additionally, I have some ideas about specific features and functionalities for the app; however, I would prefer to discuss them further with the developer before proceeding. If you feel that you have the necessary skills and experience to take on this challenge, I would love to hear from you.
