How about setting up variations as follows:
variation 1 - qty 1
variation 2 - set qty * 1
variation 3 - set qty * 2
etc
Then set up a little jquery to always protect the qty 1 1st variation when displaying the product price. I believe this should show the single unit base price throughout the system as the 'from' price, but prevent the purchase of the non-set quantities.
