Digital Fish Graphics/Illustrations

I am looking to hire someone to create somewhat realistic drawings of fish graphics that can be used for commercial use. I require around 40 different fish done, with 3-5 different orientations of each. Reference will be supplied, you must be able to draw yourself to generate required orientations. Pure AI will not be suitable. If possible, I'd like to look through mock ups or a portfolio of past work prior to awarding this project as I have a preference to the style I am looking for, see pics attached.
