Alternately, you could do it yourself. You could run the lcd in 4 bit mode and use a 74H595 serial to parallel converter, and just use the D4-D7, Enable and Register Select pins. You will then have two extra outputs on the '595 to use for turning the backlight on/off, a relay, or something else.
Or if you want to use I2C, use a PCF8574, I2C to parallel converter.
