Unfortunatly 4 layer requires plated through holes. The process for 
fabricating plated through hole PCBs is huge jump in complexity compared 
to non-plated hole PCBs. Going from double sided plated through hole to 
4 layer requires the ability to laminate layers. A multilayer PCB 
follows all the same steps as a double sided plated through PCB, with 
addition of innerlayer etching and lamination.

I havn't made a 4 layer board. I'm still working on my PCB equipment for 
making plated through hole 2 layers.
