Digital Photos Manipulation

I am seeking a Photoshop expert that can modify and manipulate 5 existing digital photographs (G1 to G5). You can download examples, plus the actual photos to be worked on here: [login to view URL] proj..zip The photos will be used on websites, so they need to look crisp, clear and as professional as they can be. My requirements are as follows: (see example images in .zip file) • Outline the person and remove the backgrounds. Make the background transparent so that the image can be used on any web page with any background color. (similar to Example 1) • Remove the facial imperfections / blemishes, redness etc. from the face and neck areas. ('Magazine looks' are not required) • Adjust contrast and light if necessary to give the best effect. • Create a light 'halo' effect around the outline as in Example 3. • Plus any other enhancements necessary. Also, some examples of past work to be supplied.
