Hello,
I've read your job description carefully and I'm pretty sure I can finish this project with Django in 2 days.
As you can check from my work history and profile, I'm an experienced and skilled Django developer.
I would hire twitter bootstrap as front-end and will quickly build Django models too.
First page can be implemented using django model/form and bootstrap's accordian.
Drag and Drop feature in 2nd page would require more work for UI, but I would consider jQuery plugin for drag/drop feature.
Anyway, I'll finish this project in 2 days (16 hours / 400 USD in budget).
I can start working immediately and looking forward to working on this job.
Best Regards,
Bruno
