Experienced New Jersey-based Pattern Maker Needed

Hello, We are looking for an experienced pattern maker for a technical consultation (to discuss the feasibility of our garment) and for actual pattern making. The garment in question is a T-shirt (ready-made), with a complicated "embellishment" that has to be made and attached to it. So we need the consultation for the "embellishment," how to best attach it to the ready-made product. And then we need for the pattern of the "embellishment" to be made. The pattern maker has to be based in New Jersey, USA.
