I would say, Lean to code. Divide your SaaS project in small unit of task, explore each section unit by some video tutorial at first-good for first. try on youtube, freecodecamp or udemy. gain knowledge of subject and make small function to demonstrate the part of your saas products capability. Explore and learn, you can later hire some dev, co-founder or CTO of tech background. For coding, I would say put your efforts in some nice language Eco-system. Python is just fine no offense, but If I were at your place I would use PHP or node. My reasoning: PHP is language of my personal preference. For node, Its basically javascript at server-side, so It requires you to learn just a single language, its features and tooling. if you are writing web app you can share codebase of many part of frontend and backend.
