Set Automator to email an attachment once it is added to a folder.

Here's my workflow every week:

1. Create invoice in Numbers

2. Print as .pdf and save to *clientname.invoices" folder

3. Email .pdf as an attachment to client.

Here's what I want to happen:

1. Create invoice in Numbers

2. Print as .pdf and save to "clientname.invoices" folder

3. Automator recognizes a new file in the folder "clientname.invoices", and creates an email with the new file attached.

4. Automator populates the email address.

4. Automator send the email with stock text in the body of the email.

I would like to have multiple scripts for multiple clients, so that if a document is added to client A folder, it populates with client A email address.

Seems like it would be easy. I can't seem to figure it out.

Thanks!
