Hire a Photoshop Designer

Art Project - Need assistance with Photoshop Hi, I am working on an art project using photoshop and I need some assistance. Here is what I want to know how to do: 1. Take an image and convert it to pixels (max 6-8 colors that I will choose). I would like to size the pixelated image to fit the measurements of the canvas I will be using. Ex: 36 in x 60 in, 48 in x 72 in, etc 2. Once the image is pixelated and resized, I would like to add very thick grid lines (squares of 8 pixels by 8 pixels). These thick grid lines should not intrude on the space of the pixels. On the contrary; they should make it easier for someone to perform grid art. 3. Once the grid lines have been added, I want to know how to take each pixelated box, determine the color that fills each box, and convert that color into either: - an alphanumeric character - a small colored dot - or an easily-identifiable symbol 4. Once this is all done, I would like the ability to view each grid box (of 8 pixels by 8 pixels) as individual grids, each one bordered by the thick grid lines from step # 2. I was thinking that one way to do this was to print the image (to a PDF document), and each page would be a grid box of 8 pixels by 8 pixels. With this, each following page would be the next grid box, either in horizontal or vertical order. I am available to provide additional information if necessary. Thanks in advance!
