This is fantastic!! Ideally i would like three versions of this. The first would be exactly how you have done the above however can you make "Destruction Services slightly more bold so it stands out against the green background. Secondly can you make on that just has the "OZ" and nothing else and thirdly one that says "OZ and then just Shredding underneath.
If you can make those three versions and send for final approval I will award the prize to you! I am really impressed.
