I'm looking for help estimating the development time for a project. A friend has asked me to build it, and before committing I'd like to get an estimate from other developers.

Based on the project description, approximately how many development hours do you think it would take?

The project is a field operations platform with an admin dashboard and a mobile web interface for field workers. It includes scheduling, Google Maps integration, GPS and timestamp capture, photo uploads, role-based access control, reporting, automated emails, in total it is around 30 pages.
