One of my clients is wants a background to match their business cards - Which is this: I know I've seen something similar before but just can't find it! Anyone?
If they want it EXACTLY the same...you might have to recreate it which would be a ton of work. If they just want something similar in style, you can create something yourself with Photoshop brushes or download a vector background from a stock photography site like istockphoto or bigstockphoto.
Search from "Abstract" keyword on these website, i hope you will the vector of this one or you could find the similar to this so that will not be tough to task to make that like this. Concerntrate more on Shapes because you can change the color later on with the help of Illustrator or Corel Draw etc. These are websites where you could find this vector shutterstock . com istockphoto . com stockxpert . com 123rf . com Try to find out this shape for free also use "Free Abstract Vector" Keyword and you will find plenty of website where you can find these type of shapes.

This is something I threw together really quick. Not sure if this is what you may be looking for or not. http://aff.bz/touchashley/
Have a look on deviant art, I have seen very similar styles to the one you are looking for, adjust them on photoshop for colours you desire
