Subtle Photo Color Balancing -- 2

I have fewer than ten images that simply need their tones corrected. Right now they swing between under-exposed and slightly washed out, so I want each file adjusted for balanced exposure, accurate whites, and a natural, pleasing vibrancy. No object removal or background work—this is purely colour correction.

Please deliver the retouched photos at their original resolution in JPEG, and include layered PSDs if you use Photoshop or Lightroom Classic for the edits. Consistency across the set and preservation of detail are my top priorities, and a quick turnaround of two days would be ideal.
