Graphic design

I have a 2graphics that need reworking and then converting into black and white for my book they look great in colour but need redrawing to work in black and white. I.e. the colours are too dark to work in black and white.

I need someone that can use Photo shop to do this in the next 24 -36 hours

I can provide the source files to save time. I would suggest a quick Skype call for me to explain what is needed and you to do it than then make it.

Thanks...There while be more work I have another 10 diagrams to make from the 2 base diagrams. I also need someone that can design the graphics for my website...that will be a separate bid.
