Application developer

I have a Cargo Van dispatch company and I’m seeking a skilled individual in this field to assist me in launching an IOS tracking and delivery app.
Looking for a logistics-friendly iOS app to manage your cargo van loads and dispatching. Seeking development of a Swift-based app for my business that allows drivers to:
? Track loads
? Share location
? Upload POD/BOL to Google Drive
? View earnings
And lets dispatchers:
? Assign loads
? Track driver progress
? Review uploads in real time

Also:
• Firebase backend
• Google Drive integration
• Clean, intuitive UI
• PDF and image uploads
• Xcode project and IPA file
Also need a web based version for dispatchers.

Most of the coding infrastructure has already been done.
I need help in testing and putting everything together bug-free and launching it on the App Store.
Willing to pay $250 to get this job done.
First half gets paid after a first working demo is shown, the rest gets paid after the app is launched. Will pay a monthly retainer fee to ensure maintenance and updating of the app. Will pay an extra $50.00 if work can be completed in 1 week.
