You should be looking at integrated H-Bridge chips, like the SN754410 from
texas instruments. There are two onboard H-bridge circuits; it'll
handle your power requirements; and, is CMOS, so it'll be much easier to
drive than a bridge made up of bipolar transistors...

It won't work down to 1.5V, but your motor will work much better at 5V
anyway, particularly if you use PWM to control the speed (which this chip
will help you with).
