MVP Support Worker Matching App Development

I'm seeking an experienced full-stack development team to build a secure and scalable web and mobile MVP for the NZ disability sector.

Key features include:
- **Support Worker Registration**: Upload credentials (driver's license, police vetting, qualifications), select skills, and service areas.
- **Admin Dashboard**: Review and activate worker profiles.
- **Job Posting**: Clients can post jobs.
- **Matching System**: Active workers receive push notifications for accepted jobs; shifts will be integrated into a worker's calendar.
- **Timesheets**: Client approval needed and exportable for invoicing.

The application must be:
- Secure and privacy-aware
- Accessible with screen reader support, high contrast mode, and text resizing
- Scalable to accommodate future growth

Please provide examples of similar work, along with a timeline and cost estimate.
