Outlook won’t allow me to have a body message with an attachment from Mail Merge?

Hey guys, I am using Outlook 2011 for Mac along with Word and Excel to send Requests for Quotes. Problem is, that I need to generate the document as a PDF and then be able to have the ability to add a body message to the actual e-mail itself.

I tried to mail merge using existing database and in 'Generate e-mail messages' the last option in mail merge, it only attaches the document as a .docx and sends it out without letting me attach anything to the body of it.

I am using Yahoo e-mail and I am so confused as Google is not necessarily helping.

How do I send out e-mails from the database I am using (excel) and still be able to attach a CUSTOM document along with a body message and other attachments.

Basically, its one trade but multiple e-mails. Every recieves the same thing except in the main document it says their company name and contact person. I am sure I am over thinking this but I am so confused that I just want to get this done. 

Please help!!
