Character Design x 10

I would like to create a suite of friendly, illustrated characters that I can use across printed materials and digital media for my clients.

I am looking to create the following as vector files and PNG formats:
- A receptionist (f)
- A practice manager (f)
- A practice manager (m)
- A GP (f)
- A GP (m)
- A physio helping a patient to walk
- A pharmacist and patient discussing medication
- A nurse and healthcare assistant chatting
- A dentist and patient in the chair
- A group including GP, nurse, physio & pharmacist
- A community support worker serving a cup of tea to an older person
- A community group - mixture of old, young etc

I have attached a similar design that I know of - I am looking for a similar fresh, friendly and colourful style.

I would love to see any illustrated characters that you have created previously and if you have any additional ideas that would work well as part of these designs, let me know.
