I need a mobile app for my brand

I am looking for a mobile app developer who can create an app for my beauty ladies salon brand that works on both iOS and Android platforms. I need someone who can help me design the app as I don't have a specific design in mind. The main feature I require is e-commerce functionality to enable users to make purchases through the app. Additionally, I would like the app to integrate with social media platforms. Ideal candidates for this job would have experience in mobile app development, e-commerce integration and social media integration.
