creating a customized debian-installer testing CD with non-free firmware that starts talking on boot and is at low priority

[Nick Gawronski]

Hi, I am aware of the unofficial network installation CD images with 
non-free firmware but wish to build a custom debian installation testing 
CD that is around 650 megs or a DVD around 4.7 gigs that has the 
non-free firmware.  I have looked into simple-ccd and debian-cd but they 
really look complex based on just what I want to do.  I wish the installer 
to start up talking and at low  priority.  Looking on the testing 
directory there is only a xfce 650 MB disc without firmware but this would 
work if speech were on this disc as I could always put the firmware on an 
USB stick.  I however would like to build my custom talking installation 
disc if possible what steps should I start out with?  Nick Gawronski
