Develop an App for an influencer marketing agency

Hi, I run an influencer marketing agency and we are looking to create an App similar to Tribe Influencers App. Features: - Influencers sign up through the App and are prompted to log in through their Instagram, and are asked few questions (name, first name, interests, demography...) - Those data need to be stored on a custom database or on a CRM (I currently use Zoho CRM) - Influencers can see current campaigns posted by brands - Influencers can chose the campaign and submit content on the App for the campaign - Influencers can receive notification when there is a campaign - Brand can see submitted campaign by influencers and approve or reject it/they can chat with the influencers - Brand can pay for the campaign through the App (Stripe) Design: - I will design the project through Sketch - You are more than welcome to help me with the design if you'd like The App should be developed for iOS. To make sure you read the description, please include $APP$ at the beginning of your proposal. Otherwise, I won't consider your application.
