I think that the CD backup idea has some potential, but would
actually take your business idea down a different path. One
reason is that most people realize they "should" backup, very few
do.
On the other hand, many computer users are feeling the pain of
hard drive fill-up, esp with the big programs nowadays. Offer to
copy their hard drive onto CD-ROM, giving them almost all of the
hard drive back as empty space.
You'll have to know which programs to delete from the hard drive
and which to leave (maybe partly by most recent access dates).
For your own sake, perhaps leave the deleting to the customer,
with a little advice given.
I know I for one would pay for a little breathing room on my HD
