About 15 years ago, I helped set up a factory in a closed auto plant to manufacture pre-engineered (structural) metal-foam building panels. The production line was 600' long, ran at a maximum speed of 1M/sec and was operated with 6 PC's. A separate space was utilized to construct custom design/build commercial structures. All engineering (including plant design) was in-house. I was the rain-maker.
My first client ordered 1,000 custom oil change buildings before we figured out how to get our on-line cutoff saw to operate (let alone make high speed precision cuts) - we had to keep shutting down the line and manually make cuts at certain intervals - lot's of wasted time and material. Because I wasn't sure of the exact costs - I added $15,000 to the President/engineer's cost estimate (per building)

to be safe - that was my compensation in addition to my production pay. Dare I say (luckily) my client's financing was sporadic and we managed to fulfill our obligations - lot's of fun! Did I mention the plant was located 1,000 miles from my home and I drove back and forth every 10 days on average?
I apologize for the long story to reach the point of relevance. We faced the decision making process you've outlined. This was a new venture - nothing to compare. Accordingly, we prioritized staffing requirements first from a minimum operations point of view up through maximum operating levels.
We ultimately determined a plant manager and 2 floor supervisors would be the most important factory workers. The President was an engineer (he designed the plant) and was capable/enjoyed designing custom projects, we identified a key administrative person, and I was charged with sales. The plant personnel and the administrative person were paid from day one. The plant could be operated at minimum production levels with these 4 key persons and myself. As rainmaker, I needed to sell roughly 1 turnkey commercial building or about 10,000 linear feet of material per month to pay all of the bills - both were do-able.
The President was vested but also negotiated a base package of about $125K with a 7 figure+ long term target and (as indicated) I agreed to a (very generous) straight commission structure - basically 2.5% of production/material sales and an exclusive distribution arrangement for select commercial segments - I typically added 25% to 35% to the factory price for custom/turnkey commercial units or residential packages and was still competitive. I've always enjoyed working in a start-up environment where the challenges have never been thought of in textbooks.
The base salaries for the key factory people ranged from $50k to $60k plus significant quality control and production bonuses. The administrative person was scheduled at $40k but also had incentives that could double her pay. We (management) believed very strongly in incentive programs. Eventually, everyone from the truck drivers to the factory assemblers and office staff had a base plus incentive agreement - everyone was paid a reasonable living wage and everyone shared in the success.
Unfortunately, I agreed to a very aggressive performance requirement to maintain exclusivities and preferred pricing structures and eventually moved on to the next venture when the in-house sales force settled into selling price instead of the competitive advantages.
