Sort into existing subfolder which contains same word

Hello, I hope you understand my problem, my English is not so good:
I want save file for example:
hello_name_customer1.ai
It should move to my server, there are existing folders of customers. (customer1, customer2...)
Now I want that haze find out in file name the word "customer1" and move it into existing folder "customer1".
Is there any way?
So:
test_customer1.pdf
customer1_text_1.ai
testtest_customer1_test.pdf
move to existing folder -> customer1
Thanks
Tobi
