Then let's get started.

002}. Go to Layers -> New Adjustment Layers -> Color Balance.
Midtones = 50, -50, 30

003}. Go to Layers -> New Adjustment Layers -> Channel Mixer. (Make sure Monochrome isn't checked!)
Red = 89, 0, 10, -5
Blue = -40, 45, 95, 0

004}. Duplicate base again. Drag to top. Set it as Soft Light 45%.

I'd love to see results!
Credit is very nice, but not necessary as long as you don't claim it as your own. =]
