Find a local cabinet maker and see what you might be able to work out with them.
I made a couple of stocks back in highschool as shop projects and like you found out in a hurry that when you are doing them without templates (there was no CNC machining back then), jigs, and equipment set up specifically for stock making it's an awful lot of work.
I started with just 2x6's and man it's a long way from a simple piece of lumber to a nice stock!
I think I ended up throwing away six or eight of them and starting over and after hundreds of hours of trial and error came up with two that were half assed workable.
You're already doing a nice job than I ever managed HA!
