Urgent search a developer iOS front end

It's WIP Music. Our startup is funded by the WING digital fund and 10 private investor, including the funder of Ogone (now ingenico). We are building an app to gather musicians, music lovers and music professionals. Including features to give tip to the artist, to book artists and to discover artists though a Tinder-like session of the musical clips you uploaded on the app. At the end, you, as a Music lover, can find and attend to an concert close to you.

The traction for the project is huge, here in Belgium. We have agreement with the 10 top musical schools. The most well known local stages venues are already using the app to list their concerts. And some national artists already have their profile created.

The app is 95% developed, in alpha tests. There are only few visual and edges cases to fixe. We also have some side flows that we'd like to improve before beta and release.

Language is ObjC. It uses Core Data. We use Stripe for payment. The app also uses location and video streaming capabilities. The API and Android is 100% operational and ready.

I urgently need a short term developer to end the development. I need somebody successful. Price is important.
