Once we've created the project page for your audiobook (or applied the audiobook service to an existing book's project page), we'll send you an order acknowledgement with instructions on uploading files to us. Once we've done that, you can:
1) Login to eBookIt.com
2) Click on CLIENT AREA
3) Click on the Book Title
4) Expand the Audiobook Services section
5) Complete the requested information, and upload your audiobook files to the "Miscellaneous Project Files" field.
Remember to be sure your audiobook files were created per the Do-It-Yourself Production portion of the following page (it's toward the bottom): https://www.ebookit.com/tools/lp/Bo/eBookIt/4/Audiobook_Production_and_Distribution
