Why sell hammers to the government for such a discount?
While the hammer is only $3k, the corresponding 5 year maintenance contract for said hammer nets $100k!
Send them a screwdriver first so you can bill twice.
And a second hammer in a geographically separate location for resiliency so you can bill three times.
Then pay contractors to blow torch rip-replace the tip of the screwdrivers after each screw turned.
