I need a product designer

The business is a sports performance gym in Arizona, and we would like to make a shirt based off of 'The Valley' shirts from the Phoenix Suns basketball team. I have attached a picture of the shirt below. We would like 'The Valley' on the shirt to be replaced. "the" on the original shirt would be changed to "Phx" and 'Valley' on the original shirt would be replaced with "Mach 1". Ideally, the new shirt would say "Phx Mach 1" Keep the colors of the shirt the same .
