Creating project folders and subfolders in Google Drive with Zapier

TLDR: I’d like Zapier to search google drive for a client name, if not found, create a client folder, then create a sub folder for the project, then create two more subfolders within that project folder.

Workflow Envisioned: 

1. Client submits form to Monday.com
2. Form triggers Zap

THEN

1. Zapier formats the info from the form fields First & Last Name (using formatter) to ensure both names are capitalized correctly.
2. Then Zapier combines the first and last name, and returns that to a Monday.com column.
3. Using the combined names column, Zapier then searches google drive to see if the client has already worked with us. If not it creates a client folder using their name and returns that URL to a Monday.com column.
4. Once this client folder is created I’d like Zapier to create a project folder (using the project title found in Monday.com) and return that URL to Monday.com
5. Once that project folder has been created, I’d like Zapier to create (2) subfolders in it, named “Materials” & “Media”. 

What do I have so far?

I have completed step 3, but I am unable to create subfolders. When I am able to make a subfolder, instead of being in the project folder, it ends up in the root directory of the shared drive.

Does anyone know how to make subfolders or a workaround for doing so?

Thanks,
