Illustration for mental health charitable organisation

I manage a not for profit creative charitable organisation and I need an illustration for the website and leaflet, we raise awareness of mental health and wellbeing and reduce stigma and discrimination and we share lived experience and build up our community, we are looking for a mind related illustration and this is negotiable and we can discuss with you the way you wish to create it and we will wish to use it on our project website and possibly a poster or flyer, we need something at good price
