I have done a little searching around and found a cool free resource for making PDFs. I use it all the time now. Unless you plan to be using it for many projects that will amount to needing it more than every 30 minutes, I have used it to create 5 projects in one day.
I have found, even when I have screenshots/graphics in my documents it holds the pictures well.

It's easy, all you do is browse, and find your file on your computer and punch in your email address. When the converting is done, a link is emailed to you. You then download onto your computer. It is already in a PDF and zipped up, although you will want to extract it to take a look.
But at least this way, if you find the graphics are not done properly, it was a free test right?
Enjoy!
