if you can make the drawings with some sort of pcb program, you can have a lot of options.
I really like itead. https://www.itead.cc/open-pcb/pcb-prototyping.html
depending on size, you can get 10 boards for $10.
if your boards are smaller, you can get two boards on the 5cmx5cm form, if they are smaller still, you can get more per 5x5 footprint.
