There isn't one because it isn't public. Maybe there are some numbers for how much SpaceX charges NASA but almost all missions involving the military or NASA cost more than civilian launches due to extra requirements. Especially so when they are not just ordered on an ad-hoc basis but instead are part of large contracts that include development funding.
I'd be shocked if SpaceX didn't treat this launch with all the care and preparation and expense of a manned NASA launch. Any issue with this launch would ground F9/Dragon and require full investigation the same as an issue with a NASA launch.
