This is more or less precisely the structure I use for managing my work.
I maintain each project as one Org file, keeping together all related
text, todo lists, spreadsheets, web pages, letters, and even files like
SVG files.  This way I can add just one file (per project) to my agenda
and not miss any tasks, and backing up my critical work is just a matter
of copying my Org files.  When needed, I also export the individual
nodes as HTML, PDF, OpenDocument, csv, or whatever.

This works very well for me, even when I am treating university classes
as projects and keeping the syllabus, instruction material, lab
material, data, tests, correspondence, and everything else together in
one file.

It was this capability of Org that first captured me as a user, and I
still know of nothing else with so much accessibility, utility, and
power.

I'd be happy to give you more information about how to set up an Org
file to export to different formats the way I use mine, but really the
information is very clear in the manual.

And of course, if you have any trouble, the list is really great.

All the best,
Terry
