Hello,
i am an illustrator working both with vector and raster graphics.
I had some experience making illustrations for medical purposes.
Please, take a look at my portfolio (here, on my freelancer,com profile) to see some examples of my work.
The price i gave in my bid is per one illustration. If I would be hired for other 19 illustrations, then the price per one piece would be approx 20 USD instead of 50 USD.
Feel free to contact me.
Best regards,
Ronaldas Gutmanas
