A friend of mine has recently started working for a military/historical publishing company and they're considering doing some short graphic novels. It would be a paying gig and possibly involves 24-32 page graphic re-tellings of historical episodes.
If they can get an good artist on board then the artist could have some input into the style and direction, but willingness to represent historical clothing/equipment accurately is key.
If you're interested please let me know by email, facebook or message here.
Cheers,
