App developer to finish cross-platform app and future developments

We have an exciting opportunity to finish an existing app, launch it and then work with us in the future to make it the best it can be. Our app is a cross-platform second-hand clothing store with several unique features. We need someone who is ideally local to Nottingham so that we can meet with you to discuss the app and work on it together. The app has a background admin area which uses Firebase, and the app is designed using jQuery.
