Need some tips on color

I prefer to give clients images in srgb as most of them do not have any color managed monitors. My print lab wants rgb. Is there an easier way to save photos in both formats? Basically I am having to save an image, then change the profile, save again to a different folder.
I am using CS5 and LR3.
Thanks

sRGB won't take care of uncalibrated monitors. However, it is the web standard, so that is what one would give folks to look at on their monitors, regardless of calibration.

I am not sure what you mean by 'lab wants rgb'. Which rgb? sRGB, aRGB, or ProPhoto? If they did not clarify this, ask them. Most labs want sRGB, but some take aRGB as well (e.g., Bay Photo). If they want sRGB, your problem is solved.
