How do I create a downloadable link from an Interactive PDF file created out of InDesign CS6?

Hello,

I created an Interactive PDF file out of InDesign and would like to make the large file a downloadable link and share it with the user in an email. I do not want to use DropBox or GoogleDrive.

The company I contract for has their own site - do I insert the file into the site or can I create a separate link for it?

I will be recreating these presentation PDF's constantly, so I would like to know if there is a simple way to create this link for files in the size of 7-12MB.

Any ideas on downloadable links? I do have flash - but rarely use, perhaps load the file out of flash?

Thank you so much for your help,

Megan
