Educational Illustrations Creation using LaTex Tikz package. Must be LaTex, not adobe software -- 2

I am writing a computer science textbook using latex. Within the book, I need some graphics, like queue, stack(for example, https://tex.stackexchange.com/questions/489987/how-to-draw-stack-and-queue-data-structure). I am in need of a skilled freelancer who can create intermediate level, detailed educational illustrations using the LaTex Tikz package.

I am still writing the book. The plan is when I need a figure, I ask your help and pay you accordingly. I expect it will be one year long process and I may need about 50 figures.

Thank you for your help.
