Hi.
I have read through your project description, I understood your requirement and I believe I can help you to ALTER, RETOUCH and EDIT your images to any required specification.
I am a professional graphic designer with cognate experience in logo design, poster, banner and flyer design, photo editing and image manipulation.
I would be very delighted to help you carry out the PHOTOSHOP tasks. You can check my portfolio for some of my previous manipulation. I'll be looking forward to your response.
Warmest regard.
