Whats your colour scheme like? Mainly for your vehicles.
I could do you a black/white version of that that Sorck (or a dedicated company) might be able to use for your transfers.
The tricky part is those very thin detail lines. At 40k scale, they'll be very faint, though with the image scaled up, they'll show better.
Eshin Grey (A darker grey) for the base, Dawnstone (A lighter grey) for armor plates and raised portions, and Troll Slayer Orange (A bright orange) for highlights. In pure black would work, though, I use black for most of my 'Logos'. (Aquillas, writing, etc.)
The thin detail lines wouldn't really need to be there, especially for smaller decals, just the dragon in the middle. I could Photoshop it to black and white if needed.
Other problem: Here's the surface I want the decal over:
Spoiler: Large image
Oh, and those metal plates on the wings will have missiles on them. I was thinking a large decal over the whole thing would look cool, but the actual icon probably wouldn't work so well.
Though, there's also this: (The largest flat surface on the ship. The Aquilla on the side can come off. Paint pot for scale.)
That would be a good place for a big circle logo, and there's one space on each side.
Oh, and finally, there's this:
Once I come up with a name for the Thunderhawk I'll put it there, though I need to decide what's going to go there.
