Can anyone help with a ballpark figure on rewiring a house?

The house was built in the 1890's and probably last had its electrical updated in the 40s. No knob and tube wiring, but there is fabric wrapped rubber. Two floors, tiny attic, and a basement. Each floor is roughly 900 sq ft. Off the top of my head I think there are 11 outlets (almost all two prong, the ones that were converted to 3 prong aren't grounded past the metal box) and 6 light switches on the ground floor, and since the upstairs has almost an identical floor plan (duplex), I would ume the same up there, but not positive.
