Graficdesign agency needed - (Read first all)

Hello, for our customer we need graphic designers for image editing. It is important to our customer that there is a solution with which he can make comments on the images eg. retouching. It is also important to make the color prove digital, which means it needs hardware for it (Lightbox,..) If you are an agency and can support our customer, please write in your answer: "Hi Dennis, yes we know". Otherwise I won't read your message, because there are a lot of spam bots here. What I need from you: 1. how do processes look like 2. what software should we use 3. how do we make the color prov 4. … The customer prepares a test, which we send to them. This will take one hour and is not paid for. The customer wants to be sure that you can complete the tasks Thanks a lot Dennis
