Perfect. Then I will tell you, you are overthinking your situation. Replicating lighting has nothing to do with what equipment you own or use. It's about seeing how the light falls on your subject and then knowing how to get the same results. Don't worry about what you think people will be expecting of you down the road. You're not there yet so give yourself permission to relax a little here.
To begin with, you do have lights. I bet I can visit your residence and pull together at least six light sources without trying. One of them, as I mentioned, is free and readily available and that is natural light. That is where you need to start. Find a window where you can set something up next to it and put something small and of interest next to it and spend a few hours photographing it. Photograph it with different looks to the light. Experiment on what you can do (with what you have) to change the quality of light. Here is your chance to think outside the box. Use a white t-shirt to diffuse the light, a white paper plate to reflect the light, how about a small mirror to aim the light, a large section of aluminum foil for a bigger reflector, light coming through a translucent plastic storage container, through a glass of water, through colored cellophane, put a table lamp overhead, put some tracing paper in front of the lamp... Get the idea?
Late on, when a client does come up to you , shows you a photo and says, "can you create something like this? you will be able to confidently and with conviction say, "YES I CAN!", rather than "I don't know if I have the right lights"
Actually, if you look at my setup photo I posted previously you will see a DIY diffuser I made with a piece of foam core (cut squared) and diffuser material (shower curtain) taped with double sided tape used by carpet installers (that stuff is thin and sticky). I made that years ago and it's still in use. I love that thing and I got it really cheap (because I'm pretty stingy with my money ). Actually, the most expensive thing in that photo is my shooting table (aside from the camera and laptop, that is). Everything else I've cobbled together over the years as I've needed it.
As a matter of fact, that same setup gave me the image I posted here; POST 18670044
