Content Creator and SEO optimiser

I am needing content creation for a psychology practice and online business (that will be opened). Content needs to follow the AHPRA guidelines and will be informative about MH (to challenge myths). Its less about advertising per say but about getting information out there.

For the online business - I will be slowly developing online educational programs that deal with behaviour change, habits and neuroscience. I will need to slowly grow an audience with posts, ?blogs (not sure) etc.

Both will require some knowledge of psychology/mental health/science to produce appropriate content/diagrams/workbooks.

Initially it will be smaller but capacity to build.
