Interactive Web App UI/UX Designer

I want to build a crowdfunding app for nonprofits that allows them to raise funds and also attract new volunteers. Need someone who can design a modern user interface in an interactive prototype for the engineering team. Basically what I need is an admin portal for nonprofits to create a fundraising page like GoFundMe that they can share with their network (via social, SMS, or email). People can then either donate directly to the nonprofit or elect to volunteer. If they choose to volunteer they can then create their own personal fundraising campaign and pledge to volunteer X hours for 1 month, then share with friends and followers to collect donations, and then split the total raised with their selected nonprofit. This 2-sided platform will need to have the following included: Nonprofit side: 1. Sign up 2. Create fundraising campaign like on GoFundMe ($ goal, deadline, description) 3. Able to save/edit/delete the campaign 4. Able to share campaign via major social media apps, email, or SMS 5. Able to collect donations via Credit Card or PayPal 6. Able to receive alerts when someone donates and when someone wants to volunteer with their organization 8. Able to contact the individual who wants to volunteer to discuss open opportunities (chat function) 9. Able to get alerts when someone wants their volunteer hours verified 10. Able to add bank account to accept donations 11. Able to update user settings (profile image, contact info, email, password) 12. A simple CRM function to manage all their donors and volunteers Participant / Volunteer Side: 1. Sign up 2. Able to chat with nonprofit about volunteer opportunities 3. Upon approval, able to create a personal fundraising campaign like on GoFundMe 4. Able to share personal fundraiser campaign with networks via social media, email, SMS 5. Must be able to set an hourly volunteering goal for 1 month 6. Able to collect donations via Credit Card or PayPal 7. Able to submit volunteer hours to be verified by the nonprofit 8. Ability to edit/delete campaign and also renew campaign for another month 9. 10. Able to add bank account to accept donations 10. Able to update user settings (profile image, contact info, email, password)
