Improvements and fixes to iOS SwiftUI augmented reality app for museum

I’m looking for a truly expert iOS developer experienced with ARKit, RealityKit, AVKit and ReplayKit. We have been developing an AR app that plays videos on anchors and allows users to place and manipulate 3D objects for mixed-reality photo ops. To do this app we are using the latest and greatest from SwiftUI and RealityKit, but we also need elements from the old UIKit and other frameworks to enable photos and videos through our app. I’m looking for someone who can mentor me as we run into issues.
