I would like that I feed the freelancers "raw" information, and that my freelancers comes up with:
- Structured requirements.
- Top/Down design / architecture.
The above should be refined as the project advances.
Actual hours should be matched against the planning.
It should be possible to reallocate work between freelancers.
Possibly the framework should support working in a Scrum / Canban way.
Otto, I think your question may not get its best answer here. I suggest you post this question as a job posting and ask for somebody to consult with you on an hourly basis.
