I would start with Dr Scheme (now called Racket/PLT Scheme). That is what CS301 at UT Austin started with https://plt-scheme.org/ back when I was an undergrad in 2000
You can definitely operate a profitable startup/any sort of business if you can find enough college grads/cert drones who are desperate for work, will take $15/hour, are "dumb and ready to fuck" and will put up with a team of unprofessional micromanaging assholes. You just to have to make sure you are their leader!
