Expert Photoshop Pro for Photo Enhancements

I'm in need of a seasoned professional who is adept at using photoshop to help transform my photos. There are no specific areas of photo editing that I need help with- your work can range from retouching, enhancing, background removal, to colour correction. While proposals detailing how you plan to approach this assignment are acceptable, I'm particularly interested in your experience. Please share your past photoshop projects, especially those where you worked extensively with PNG files. Knowledge and proficiency in handling PNG files is a must. Allow your past work to demonstrate your skills and dedication. This should not just be a job for you, but a craft you continually perfect.
