edit images in photoshop

i have four or five high quality portrait photos for which i need some editing: * remove background * add some gradient or texture background * add some overlay and edit channels so that i get a similar look about like the large images here (see full size screenshot or live demo): <[login to view URL]> in the end i'd like to replace the five images used in the templates with some similar look of own photos that i already have. if you need more information, please let me know. thanks a lot. martin
