Display Graphics Design

I need a high quality graphics support for a large (112.4" x 89") trade show display. I have an idea of what I want, and will provide the image, logo, and fonts. I have already created the document in Microsoft Publisher, but the saved file resolution isn't high enough (the logo has jagged edges) and the side bars won't save (no idea why). The file I send to the display company must be at least 300dpi. I believe the file needs to be replicated in Photoshop or Adobe Illustrator, then saved as a PDF file. I will attach the PUB file so you can see what I came up with. If you have recommendations or a better idea, I'd like to hear about that too. I will provide the stock image, logo file, fonts, publisher file, and instruction sheet from the display manufacturer to the winning bidder. Thanks.
