Is it possible to export a non-vectored .pdf?

Hi Y'all.  I've never posted here before so I hope you can help me out.  I've searched for this topic but did not find an answer.

I would like to export my Corel Draw X6 file to a .pdf., but is there an option that will make it non-vectored?  I'm a sign designer and often need to create multi-paged .pdf's to submit to architects and customers.  But in giving the customer the .pdf I've now basically given away all of my vectored art.  Anyone with Corel Draw or Adobe Illustrator can simply import the .pdf and now they have all of my artwork in vectored form.  Obviously I can export single pages as .jpg to solve this issue, but for multiple pages, and for contractual reasons I'm required to submit .pdf's to the architect or customer.

Is there a way/setting to export to .pdf, and have it be a simple, rastor-like image, that contains no vectored information?

Thanks,Matt.
