it helps to start with putting someone in front of the camera that is not only good-looking, but also comfortable with being on camera and maybe even somewhat experienced. for example acting students and singers, that's what I started with and I really can't recommend enough trying to find someone like that - call up all musician friends or people who work at theaters and have them introduce you to people as their "photographer friend" and you'll get someone in front of the camera in no time even without any sort of portfolio because actors and musicians need pictures all the time.
then even if you have no clue what's going on you will get some nice pictures, because someone experienced and relaxed will help you a tonne to do so.
you'll get some pictures you're proud of, build confidence in working with people in that particular setting - I still can't talk to some people for shit but I sure can when I have a camera in my hands, and most importantly you'll get some experience with all sorts of lighting types, poses and shooting conditions you'll face.
don't worry too much about building a "proper studio" or preparing gear for all kinds of circumstances you've never even shot before, you'll do fine with what you have and build experience and confidence on that which in the end is way more important to people for you to be confident about what you're doing and what you can offer
