Ok, 23 years selling experience, great! That's a valuable and marketable skill. So maybe first, we drop the word selling, I never liked that term, and substitute problem solver. When I smooth talked my way, from Plant Controller to Salesman years ago, I would tell prospective customers that if I couldn't come up with several non-price benefits to justify them switching to my company, then they should just throw me out. I told them I wanted to be there go to person for packaging problems. Sounds like that's what you like to do.

So somehow you have to find a problem solving job that actually pays a salary + commission. All the sales jobs that are easy to get like Real Estate, or Car Sales are easy because it's no skin off their butt if you fail.

You probably have already done this, but you have to ask all of your network for ideas.
I'm not really recommending this because it's as cutthroat as it gets, but packaging sales can be quite the creative challenge. Maybe even an inside sales job could work out. I would think you ask everyone you come into contact with as to whether they know of any good sales opportunities.

Wish I had the answer for you, but at least you have the experience.
