Hello there! :)
Given the brief description, this sounds like exactly what I've been doing for work the past year--- working for major distributors producing graphics mainly for tee's, but not limited to other types of garments or merchandise. That and I am a professional fashion designer with a BFA in the top private design school in the country. I am fast, communicative, and efficient. I am definitely your designer!
Please clarify if you are looking for someone to design a jacket, or create the graphic for the logo to go on the jacket :)
Look forward to hearing from you!
