Comprehensive Condo Management System

I'm looking to develop a robust condominium management system. The main goal is to efficiently manage residents, units, and maintenance requests. Needs to be easy to change as needed for announcements, photos, PDF documents for residence to view, etc.

Key Features:
- Maintenance Request Management:
- Residents can submit requests with photos
- Track request status and updates
- Receive notifications upon completion
- Tracks maintenance data including priority level, maintenance hours spent, cost, and inventory used

- User Access:
- Property managers and staff
- Residents and unit owners
- Maintenance workers and service providers

Ideal Skills and Experience:
- Experience in developing management systems
- Proficiency in user interface design
- Strong background in database management
- Familiarity with mobile-friendly platforms

Please provide samples of similar work and an estimated timeline for completion.
