If I design a ckt board would etch one for me?
I have recently come to learn that etching a pcb is one of the easier things to do around here.

If you can handdraw it, then scan it into the computer. Use a laser printer to print it on glossy photopaper. Iron it onto your copper clad board, then remove the paper and etch in muriatic acid available at the local hardware store. This is the basic simple process which I have condensed from Tom Gootee's website. It is much easier than, say, getting Jacco to be serious, but not quite as easy as matching bipolar transistors!

I have started working on an aleph PCB, but it will be for a cascoded J-fet.

Seriously, i've got a old flatbed plotter that puts the artyfarty straight on the clad boards, no need for paperwork.
Me missess found it in the dumpster, with ~50 plotter ink pens.
