Sorry it's the only picture I have.
The aircraft is almost certainly a Beechcraft B200 or B200C King Air, with a combined Cargo-and-Airstair Door, as can be seen in these photos:
The airstair door is essentially a door-within-a-door and opens downwards as usual:
The larger cargo door opens upwards: (source)
Looks like a Beechcraft Super King Air
Judging by the amount of windows it is not the regular King Air
