I'd recommend a reciprocating saw (Sawzall) with demolition blades. You
should be able to find a decent one for ~100. If this is for one time
use, consider renting.

Demolition blades do exist for circ. saws, but I don't know how common
they are in 7-1/4". Fire departments use these for opening up roofs --
most likely 10 or 12 inch blades in a gas powered saw.
