Welcom to the forum David.
I'm afraid that finding rungs in the exact size that you need them would be next to impossible. You do have a couple of options though.
1. Find a fellow woodworker to turn them for you.
2. Buy and inexpensive lathe off of craigslist and turn them yourself. You never know, you might get addicted.
3. Try and contact the local high school shop teacher and see if he/she can get them turned for you. It's a bad time of year for this option though.
