Startup Idea: Publication Tracking Software for Freelance Writers

Startup idea to develop a Windows-based software that could act as a comprehensive hub for freelance writers, consolidating features like tracking contacts, submission requirements, pay rates, drafts, and editorial comments all in one place.

I am a freelance writer.

I have to use multiple pieces of software to track contacts, submission requirements, pay rates, kill fees, submitted documents, editorial comments, etc. If there was a single hub that would be great. Right now I cobble my own thing together with spreadsheets but cells don't give much opportunity to encapsulate in-depth details.

Yes, I would absolutely pay to solve this.

I need Windows software that will allow me to store drafts of articles, notes of my own, submission details, rates, fee schedules, publication details, etc. There is NO publication tracking software on the market.
