I did some quick messing around and came up with the following starting point:
Using the 10 point char creation system is helpful because Ork is a C (2 point) pick.
4 - Attributes - 24
2 - Race - Ork (0)
2 - Skills - 28 / 2
2 - Resources - 140,000
0 - Magic - Mundane
Attributes
Body - 7
Agility - 5
Reaction - 6
Strength - 6
WIllpower - 3
Logic - 4
Intuition - 4
Charisma - 2
You'll need:
Control Rig - Rating 1 - 43,000
Smartlink - 4000
RCC Rating 4 - 32,000 or 34,000
This should leaves enough money to get a vehicle of choice and a few drones.
Your top skills should be:
Pilot Ground Craft (Wheeled)
Automatics
Gunnery (Balistic)
