Build an iOS App with push notifications, trying again

Bringing this back as I was unable to find anyone to do this last year…

What would you like done?
A native app for our community with push notifications being the key feature. A couple of other simple features to get it past the app store requirements, this would be a simple photography-related calculator, etc. or if you know of another way around this, great.

Background: I previously worked with pmusaraj to develop an app using OneSignal which was initially approved but then an update was declined because it was not unique enough since it’s basically just the webapp. So, much of the groundwork may be in place if we were to still use OneSignal, or open to other options. I have an apple developer account fyi.

When do you need it done?
End of August

What is your budget, in $ USD that you can offer for this task?
Can be discussed depending on what existing code can be used.
