This is not Adobe. We own no stock in the company and am not affiliated with it in any way. This is user to user. And, contact information should not be included in your thread to avoid nuisances from spammers and the like. We are glad for the opportunity to be of assistance, but the help comes from within the Adobe Premiere Elements Forum structure.
1. What version of Premiere Elements do you have and on what computer operating system is it running?
Each of the versions comes with many disc menu themes. So, I would ask "Do you have the full amount for your version? Or, are you just not satisfied with the many choices that come built into the version that you have?
2. The most obvious Adobe disc menu that comes to mind related to your stated interests is Aquarium which has been included with recent versions. Have you seen and or used that one.
You can customize backgrounds and text within the disc menu customization section of the program.
For deeper customization, then you probably will have to edit the main menu .psd and the scene menu .psd, using Photoshop CS or higher.
If you get lucky, you may find a version of Photoshop Elements on some version of Windows that will open the Layer Sets of the .psd files so that you can get at the files you seek to edit.
I have done a lot of work in the area of disc menus for Premiere Elements. Some of the work can be found
Please review. We will be watching for fine tuning of your details in the thread.
