Well, it is not the best place to get members for your VA, maybe you could try a general aviation forum, or register your VA to IVAO/VATSIM and they will surely find you.
For stuff like repaints and add-ons, I would recommend avsim.com and fsplanet.com for first sight, they have tons of military aircraft models and repaints. You could also check other military VAs, like "US NAVY virtual" and similars, to find out what they use, and how.
I hope I could help a bit
