Looking at your package, the images and included fonts take up most of the space.
Just a suggestion:
1. Replace your photos with simple monochrome pictures placeholders (highly compressed). This is a total of about 200Kb.
2. If fonts are not absolutely necessary reduce it or use external web fonts, max 10 -20 Kb.
It all comes in a zip archive and will probably not be more than 500Kb in size. Including an install folder, which will be deleted automatically after installation.
And the content of the "data" folder does not need to be copied, you can create it during the installation (on the fly). An IM based auto-installer is strongly recommended, but needs to be written first.
PS. ItemManager is already a builder, it creates its content (including fields and categories) at runtime. But for this you need good API knowledge. IM-3 is much more flexible for this.
