What??? I'm not sure you understand what I'm on about. How am I supposed to
push the component legs through the PCB without holes?
>I'm sure you don't want to have a bottom layer only pad, with a drill?
Yes that's what I want. pads and tracks on one side only and unplated holes
through the pcb.

I don't see why not? I've seen hundreds of single sided pcbs like this.

Actually we supply the .pcb file (allot of ppl in Australia do).

No. We have a very long standing relationship with this one particular
company.
Please keep your advice Protel related.
