Industial Chemistry with fosus on dyes, inks and coloring solutions

Hello, I'm seeking someone with expertise in chemistry, specifically coloring solutions used in writing pens and markers. These would be the quick dry permanent markers in different colors. Your job is to advise on which formula would be best to use for a certain application, source the data sheets and safety information and at least three suppliers of the colorant with the correct formula. I look forward to your bid.
