Copy and Design for Poster for a Psychology Class series in a gym - Gym Psyc!

I need assistance marketing a series of psychology classes in a central London gym. The gym manager is happy to put up posters around the gym A4 size.
More broadly I will need assistance marketing my psychology business.
For example, Pub Psychology - https://www.meetup.com/Pub-Psychology/
I need an A4 flyer for this Friday afternoon and another one for two weeks time.
I can provide basic details for the first flyer tomorrow morning.
Find attached my own previous version which was an introduction to the series of classes.
Target market is young professionals male and female but particularly women as they are often more interested in psychology.

Do let me know why will you be a good fit for my requirement.
Many thanks
Nic
p.s. I'm out until 9:30pm this evening delivering a gym psyc class!
