I need an illustrator

I am interested in hiring an illustrator to connect the three elements of my new programme across my website and marketing materials. The programme is all about social connection - through a survey, then a communication tool and finally an 8 week mindfulness programme. I already have my colour scheme, but would love to have some images that can create continuity through the programme. The designs would need to reflect the connection theme, but also the science backed nature of the programme and be attractive to corporate buyers.
