[ubuntu-uk] Help with custom live CD please?

[alan c]

I have a window of opportunity to attract attention in a large charity 
I have helped in the past, and I could very much use a custom (Ubuntu) 
live CD with a only a few differences from the standard:

The boot splash logo, the in-process (Usplash?) screen, and the 
default wallpaper (as live CD).

I have been trying over several long and so far unsuccessful days to 
follow some guides, and they are excellent, but success is still 
beyond me, also I tried reconstructor - almost perhaps, but still not 
working for me.

I may only be missing a few vital points of understanding or skill. At 
least now I am able to use qemu (a first for me) I have stopped making 
coasters.

Can anyone offer some hand holding about this please? I would like to 
be able to do it, but If a CD magically appeared by some other means I 
could change priorities from trying to create the CD to trying to 
influence the Charity.....
