Illustration needed for cancer workshop (NHS)

Hello.

I am a cancer nurse working in a large regional cancer unit. I am part of a team that delivers anti-cancer treatment (including surgery and chemotherapy) to a huge cohort of patients.

I am part of a team developing a new workshop that patients undergoing cancer treatment will attend. The aim of the workshop is to help patients understand what will happen to them during their treatment, how the treatment is administered, side effects encountered and when to call for help.

We are keen for the workshop presentation to be highly visual, with illustration replacing the wall of text, and therefore really engaging people so they absorb the information.

We need some illustrations of a patient, and each slide would focus on a different aspect of his treatment. For example, the side effects slide, we require a body map with some internal organs and body parts. i.e. https://i.pinimg.com/736x/60/3e/3d/603e3d5df32888d06e43ea1ca0e8d129.jpg

But we'd also like this same patient to, on other slides be, say, sitting in a chair receiving a drip. Or eating a sandwich.

We don't need anything too detailed. A basic cartoon would be sufficient. We have a general idea and can discuss further if anyone requires more info.

Questions:
1) What kind of price should we expect to pay for this work? (I think it would be about 10 different postures/drawings)
2) What copyright stuff do we need to know? For example, if we wanted to share this with other hospitals, what permission would we need? Could we even do this?
3) Any offers or pointers?!

Thanks ever so much,
