Startup Idea: Work Schedule Generator for Freelance Writers

Startup idea to develop a software solution for freelance writers with multiple clients; enter estimated project durations and deadlines which the program uses to generate a manageable work schedule.

I'm a freelance writer and sometimes, when I have a lot of clients, I have trouble with time management. Its hard to schedule around so many different types of clients without getting overwhelmed. An ideal solution would be program where I could enter in how long I think each project will take as well as the deadline, then the program generates a work schedule for me.
