Book Cover

I am self publishing a book. I need a cover designed, spine and back cover layout. (spine is just text and back cover has summary text and design if you can come up with something simple that matches front) but what Im really focused on is the front cover. Its a urban fiction novel and all of these novles tend to have the same cover. I'm looking for something out the box different but still reflects the story. The title is All Money Aint Good Money: A tale of greed It is a story of 2 women who are from total diff lifestyles and meet and become best friends. The story follows them and shows how the need and greed of money effects them both differently. One of the girls let the greed of money consume her life and it soon spirals out of control, while the other girl comes to the realization that money isnt everything and that there are better ways to get it other then selling your soul for it. It features the typical themes in urban novels (money, murder, sex, drugs and betrayal) but i dont want the cover to look like every other urban novel that just throws a model, money, cars, and money on the cover. I want something abstract and different but still reflect the theme
