The designs which another fiverr.com seller did for me are here --

He did (2D and 3D) front-cover and a back-cover.  I will call this the "original artwork."

Now is Nov. 30th.  The design work which I need is as follows.
1) For the "original artwork" front-cover, I need to have the lettering of --
Volume 1
added in some attractive fashion.


2a) I need to have the front-cover design and back-cover design for
Volume 2.

This should be in a very similar style as for the "original artwork" of Volume 1.
==> So, for the front-cover design, you need four U.S. military type pictures. (You should find 
uncopyrighted pictures.  I would assume that the U.S. Dept. of Defense website probably has suitable uncopyrighted images.)

2b) For Volume 2, the lettering in the center area can be copied directly.

2c) For Volume 2, the back-cover design needs one U.S. military type picture.  There is lettering to be overlayed on top of this picture. 

The lettering for the back-cover of Volume 2 is here --
