Plastic Ornament Name Repainting

I need a one-letter correction on a small Hallmark Keepsake ornament (about 4–5 inches tall, painted plastic). The red-bordered sign at the top reads "NIKKI'S QUILT SHOP" in white letters on a green background. I need the first "K" in NIKKI changed to a "C" so it reads "NICKI'S QUILT SHOP."
