Create disk image with Autorun.inf and custom windows/icons for Mac and PC

I need to create a disk image for a promotional USB drive containing some HTML files. It needs to work on both Mac and PC, with basic customizations for each platform: PC: [login to view URL] to launch html file Custom window background (I will provide a PNG) Custom icons (I will provide PNGs) Mac: Auto-open disk window when drive is inserted Custom window background (I will provide a PNG) Custom icons (I will provide PNGs) Hide all Windows-specific files (such as [login to view URL]) from Mac users To clarify, I need to create a single disk that will work on both Mac and PC. I will also need you to provide instructions on how to save the disk image to a test drive using a Mac. From what I understand this involves the UNIX Terminal. I would like to work with someone who has done this before. Please note in your bid if you have created a Mac and PC disk before. Thanks for your interest.
