Book Cover and Art for CreateSpace Book

I am an author in need of artwork/cover for my second novel. My first novel is visible, here, on [login to view URL] (http://www.amazon.com/Shadow-That-Endures-Fernando-Torres/dp/0615895840/ref=sr_1_1?ie=UTF8&qid=1419634509&sr=8-1&keywords=The+Shadow+That+Endures). I will need a cover featuring a group of nuns, carrying rifles, on a medieval bridge (it is a book about a group of nuns who join the French Resistance in WWII). It will need to be to the specific size and formatting (as required by Create Space [this may take a couple of attempts, included in the price). I also require a title page inside (using the same font as the cover), with a small illustration. Lastly, I will need a small illustration for the last page of the book. The feel for the artwork should be WWII-era. Be aware, that as a self-publisher, I will need to retain all ownership/copyright of the artwork, but you may, naturally, use it for your portfolio. The files I have added give the flavor of what I'm looking for: A group of nuns standing like in the Band of Brothers photo, standing on the bridge. The picture of the nuns gives a idea of their look, but not their pose and specific body styles (which I will provide). Thank you for your interest.
