Photo Enhancement for Wallpaper

I need a photo enhanced to a high level of crispness. The image should include a bed and a person in it, but I want the background to be a plain wall or something equally simple to make the subject stand out—ideal for wallpaper.

Requirements:
- Background: Light gray, solid color
- Subject touch-ups: Skin smoothing, teeth whitening, blemish removal, and achieving a nice skin tone
Good lighting
Ideal skills and experience:
- Proficiency in photo editing software (e.g., Photoshop)
- Strong attention to detail
- Experience with portrait retouching and background modifications
