Help with subfolders

I'm really new to Hazel and am having a hard time! Please use very simple language in any response. I'm in Kindergarten when it comes to Hazel!
I have many clients who have five main files that look like this:
1. Older Files
a. Older Financial
b. Older Therapy
2. Billing
a. Doc created 6/12/14
b. Doc created 2/12/15
3. Checks
a. Doc created 6/12/14
b. Doc created 2/12/15
4. Docs from therapy
a. Doc created 6/12/14
b. Doc created 2/12/15
5. EOBs
a. Doc created 6/12/14
b. Doc created 2/12/15
I want to be able to move the documents that are older than 6 months into an "Older file" so that I can easily find the recent documents I need. (Archiving to zip won't work for me.) But, the laws in California require that I keep therapy documents separate from other documents. So, in the example above, I would like the files created on 6/12/14 in that are in the "Billing", "Checks" and "EOB" folders to be moved into the "Older Financial" file. But, I would like the 6/12/14 document in the "Docs from therapy" folder to be moved to the "Older Therapy" file.
What is the easiest way to do this with the fewest rules possible?
