Hi,
I agree that single sided, single layer,no vias,no holes, no soldermask, no legend makes it very easy, so easy in fact.................
maybe........ depending on the component density and signal widths, isolation width to the ground plane, you may find that all you need is some presensitised board, a cat litter tray, some etchant and a printer capable of laying on a dense image onto a translucent paper/acetate. Oh and the sun shine for UV source, if you are lucky.
you say the boards are assorted and you mention one 1/2" x 9" well its the panelisation that is going to take time. Will your layout software allow you to arrange multiple designs onto a single printout?
I know this is not the answer to your question but i'm sure you would be able to succeed if you gave it a go, you could have a design from screen to bench ready for populating within the hour, how cool is that.
