Bring my artwork idea to life

I currently have an idea for a (mainly black and white) artwork that I'm looking to have created. It is of a yellow-tailed black cockatoo and a sulphur crested cockatoo sort of intertwined to create a yin-yang. One will be right way up and the other head down. I'm looking for a more realistic design. It will be for a tshirt back so will need to have transparent background.
