I used LTSpice, which is free and first rate. Although it is a fully capabl=
e Spice simulator, the libraries are fantastic. I switched to Linux in 2011=
, so haven't used it since then.

I'm curious, does your customer need to originate a drawing himself, or wil=
l he just need to make mods to your supplied drawings? If you supply the or=
iginal drawings, then modifications by the user are quite simple.

I also had good luck with a pcb drawing schematic offered by several offsho=
re custom pcb manufacturers. They require the schematic be entered first, t=
hen the user can drag etches to do the layout of pcb traces. They have gene=
ric boxes for chips where you can change number of pins, chip name etc. I d=
on't remember the name of the vendor, but I got mine from a custom pcb manu=
facturer in India. You can export the project without actually doing the pc=
b layout, which means you can use it without having to enter chip numbers/p=
ackage types.
