Build a Crowdfunding Web App + Android + iPhone App for Zambia

Project Title: Build a Crowdfunding Web App + Android + iPhone App for Zambia

I need a developer or team to build a crowdfunding platform called Nimwe na Inwe (“It’s You and Me Making the Difference”).

This will be a GoFundMe-style platform for Zambia, but focused on verified and authentic causes only.

What I need built:

Web application
Android app
iPhone app
Admin dashboard

Main features:

User registration and login
Users can submit a cause with:
Title
Description
3 images
Optional video
Location
Amount needed
Guarantor details
Verification system using trusted guarantors such as:
Church leader
Police verification
Community leader
Admin approval before causes go live
Public cause listing and search
Donation/payment integration
Cause detail page showing verification status
Notifications
Secure and simple design

Important:
This platform must be built around trust, so verification is a key feature.
