IOS help for React Native project

I'm looking for an IOS developer with experience working with in-app purchasing (particularly subscriptions) and setting up products on Itunes Connect to jump in and consult on an existing project. The project will consist of checking that we have set up the purchases correctly on Itunes, going through the process with us and then possibly modifying the code on the react-native plugin if need be. Please let me know what relevant experience you have. If you have used react native before that would be great, but it's not a prerequisite. Please also send over your hourly rate - it's largely consultation rather than coding so make sure your rate takes that into account and you charge enough to make it worth your while!
