It looks like the minimum requested cargo space (10 Special Compartments) amounts to two "Cargo Spaces" (each giving +5), for a total of 2 Cost and 2 Compartment.
Aurek Design
Ship Class: Light Freighter / Armored Courier
Compartment: 40 / 50
Speed: 50 / 75 (R5)
Maneuverability: 50 / 25 (R3)
Weapons: 0 / 10
Special Compartment: 10 / 10 (R2 for Armor)
Cost: 30 / 35
Starting from here - where the only thing missing is the Cargo Space - we have the budget for 5 Cargo Spaces, but we could easily provide only 50% more space than requested (only 3 Cargo Spaces) and still be 2 cost under budget with 7 spare compartments.
But those requirements are meant for a mere Courier.
And Couriers are not meant for bulk shipping.
The expectations for a proper
freighter are likely to be different, with a whole lot more dedicated cargo space needed.

If we grabbed only one engine, one hyperdrive, and one armored plating, the stats on the Aurek would be:
Compartment: 20 / 50
Speed: 30 / 75 (R3)
Maneuverability: 30 / 25 (R2)
Weapons: 0 / 10
Special Compartment: 5 / 10 (R1 for Armor)
Cost: 15 / 35
From there we'd have the budget to add
20 Cargo Spaces to it for a total of +100 Special Compartment, and still with 10 Compartment left over.
That seems much more like what a dedicated freighter would run.
It seems to me that we are best served by making a ship dedicated to only one of these two roles, and not trying to make it serve both.
Edit:
Also, I'm warming up to the idea of our trademark being putting more armor on things than you'd initially expect.
