ASAP Background Removal for 3 Photos

I have three high-resolution images that need their current backgrounds cleanly removed and replaced with full transparency so they can drop straight into print layouts. Edges must be crisp with no halos or color fringing, and the final files should retain original dimensions and resolution...
