Real Estate Agent Task Management System

I'm looking for a task management system specifically designed for real estate agents. This system should facilitate the management of tasks related to property closings.

Key Features:
- Automated reminders to keep agents on track
- Document management capabilities to handle all necessary paperwork
- Task assignment and tracking to ensure every task is accounted for

Platform Requirements:
The system needs to be compatible with both Web and iOS platforms.

Ideal Skills:
- Experience in developing task management systems
- Knowledge of real estate processes
- Proficiency in Web and iOS app development

Please only bid if you can deliver a system that meets these requirements.

I want to keep track of real estate closings. There are approx. 6-7 tasks that are accomplished one by one in about a 60 day time frame. I have 10 to 20 closings happening at any given time. I want to see the big picture in a spread sheet that is graphically pleasing and nimble. I want it to expand to see more detail on certain tasks - then collapse to keep seeing big picture. I want colors used so it's easy on the eyes
