Regardless of the final output options, most labs will not pull process C41, not any more. For non-digital solutions to the contrast/saturation issue, I'd second/third/fourth the previous recommendations of altering the lighting in the scene with diffusion and/or reflectors (1st preference), fill-flash (distant second - unless you know how to control it, it won't alter the saturation, just the overall contrast), and very distant third, expired film - look for stuff that's over 10 years past date, so that it needs additional exposure. The great risk with the expired film technique is that the conditions in which it was stored and handled are unpredictable, so you really don't know what you're going to get - if it was frozen, it may not have a perceptible loss, but if it was stored in a metal cabinet in an un-airconditioned garage, well... it may have significant degradation.
