I agree with Wes who has gone out of his way to give you a great way to improve upon your skills. Irtar has also pointed out a good example for you to review. I would even add to your original post at the beginning of this thread supplying more examples of your idea and what angle your company intends to specifically be involved in. (ie. location, droid models, who your inteded buyers and/or partners will be and so on)
When you say
faction, do you intend to start a true faction meaning you have two other members to support you in this faction or are you just wanting to start a simple company to roleplay with? I only ask before someone else does and to point out if you are requesting to start a true faction, you'll need to be alot more descriptive with your plan than what you have here. (ie.
The Nightsisters)
I think this is a great idea for you. I did the same type of thing a while back with
Arahsi Incorprated so feel free to use the format as a model for yourself if you would like.
So, as Titus said, go ahead.
Good Luck.
