Convert PPT/PPTX to high quality PDF

I need my PowerPoint File (pptx/ppt), to be converted into a high quality PDF. The PPTX File is full of PNG Images. Everytime I try to convert it to a PDF I lose the quality of the PNGs or the PDF gets crazy scales. So i need someone who can convert my PPTX File into a good looking PDF with full quality images, without weird borders or something and it should fits perfectly to a desktop screen, so users could read it like a eBook. Also I must be able to add some additional customization afterwards (some hyperlinks with Acrobat). I attached a demo file of the PPTX so you can check it out. You get the complete file to convert it when you get the job. Thanks in advance! Alex
