I am a Senior Level Graphic Designer with several years of prepress experience, currently living and working in Florida. I understand, fully, the process of making press-ready artwork and changing colors within images to spot (Pantone) colors.
I would love to talk with you about completing this job and any future projects you might have.
Since I haven't actually seen the art that is going to be converted, it is more difficult for me to give you an exact time frame in which the job will be done, but I can't imagine that it would be something that would take longer than an hour, so my completion time should be within a few hours of being awarded the job.
