Yup. Trick is not to hire anyone until your 1st health potion is tier 2 (potions with health stat will sell for higher price). After that try to hire someone with procurement at 9 or above
Anyway, I have added contracts and fluctuating market for the latest game build.
Do you mean Job skill? (each job requires a specific skill. for example, production worker needs production skill. Amount of potions produced are dependent on the production skill. You can upgrade these skills using HR -> Training.)
