Font viewing on iBooks and iPad in general

Hello there, I have the following problem:

I am writing a book in a PC using Word 2010 in Windows 7. I am using two different fonts that I downloaded off the internet: Lancaster and Fertigo Pro. So I saved a PDF and tried viewing it in my iPad, first in the mail and then in iBooks. The iPad, however, shows a bunch of black blurred rectangles instead of words either in iBooks or in the mail. I then tried converting te file to epub, maybe an iBook would display the font correctly, but nothing.

Is there anyway I can view my file in my iPad, most preferably in iBooks as an ebook?

Also, I have absolutely no problem viewing the file in my PC as either docx or PDF.

Thanks.
