I need an app developer for both ios and android

I want to make a shopping e-commerce where this app will be equipped with live streaming and also, the vendors can post their edited photos and videos through their stores in the app. This app also can be used to edit videos and pictures like Ig and Tik Tok.
I can give you a little bit on how the app would have from this wireframe I made.
