Comic Hero Style Event Invitation about Money Worries

I need a graphic designer to help us design an invitation to staff money advice sessions. We have an idea of what we would like to create particularly as this subject is usually dry and unengaging. We want a bit of pizazz but not too much given that the audience is likely to be people 35-55 in low paid stressful jobs. At the moment we don't have all the text and will need space for dates, locations etc. I will attach the 'moodboard' and can talk though the requirements. We hope to end up with A5 leaflets, A3 poster, something suitable for an intranet page and possibly What's App.
Please do attach an example of anything similar if you have it.
