build 30 ios apps

I am looking for a developer to help me build 30 iOS restaurant apps within 4 days. The developer will need to be experienced in building iOS applications using the latest version of Swift. I am open to the idea of using cross-platform in order to maximize efficiency where applicable. The apps should include clear user interfaces and interfaces that are optimized for both smartphone and tablet users. The apps should show strong attention to detail and fast, reliable load times on both types of devices. The current timeline for the project completion is 4 days, so the developer must have the skills and expertise necessary to complete the project within that timeframe.
