I originally thought you were wanting to sell fine art photography of guns. Now when I reread the post, I am not sure if that is your intention, or if you want to sell guns online.

If it is #1, then go with my original post.

If it is #B, then literally any point and shoot digital you buy today is fine. No need to even spend $100 to get pics plenty good enough to sell guns.

If my first interpretation of your intent was wrong, then I am sorry about that
