High-Quality Picture Enhancement

I am seeking an experienced photo editor to adjust the brightness and contrast of a personal picture, retouch blemishes, remove unnecessary filters and people from the background. I need this edited photo in high resolution (300 dpi), suitable for personal use. Ideal skills required would include proficiency in Photoshop or similar image editing software, with a keen eye for detail, ability to meet the specific requirements and background in photo retouching.
