we are wondering if some experienced modders would like to work with us, the game is pretty much perfect to be modded off
How can you say that without having experience with it? I have experience and I would recommend any new modder to go to another game entirely. Sins has literally nothing attractive about it in terms of modding, something you will discover if you actually get balls-deep into it. Actually, I would recommend to steer clear of modding in general, and pick up the UDK. You will accomplish far more and there will be little that isn't possible for you to do. That is if, of course, you actually have the drive to learn and spend time on something. Most people don't. That's something you should figure out before wasting your time on any mod or larger project. If you're busy, chances are it won't work out. Don't start a project hoping to rely on someone else. That is guaranteed to fail immediately.
Your best bet is to aggressively search with the forum's super effective and reliable search function.
since you can pan around the ships, there are gun sounds and missile sounds, a nice variety of ships with roles.
That describes, like, every RTS ever made. The "roles" in sins don't actually mean anything, either, except in regards to internal AI calculations. They're just text. An effective role is what you make it.
Besides, there's already a decent BSG mod that would take an inexperienced modder maybe a day to update if he searches around.
