There are a number of PCB prototype and small series production outfits 
on the web (Google seems to find them very well) that can give you very 
reasonably priced multilayer boards with surprisingly low turnaround 
times. If you use one of these outfits for your PCB needs anyway (I 
have no desire to have the chemicals at my place, the tools to do PCB 
layout transfer and etch properly are not eaxactly cheap either and 
then I still don't have proper through-holes or vias), then even when 
you manage to squeeze everything onto two layers, it may be better to 
spend two extra layers for proper supply planes and/or to 
avoid crosstalk between signals.
