Yes i do have another live preview since i got 2 customers, im selling the source code so you can hire devs after me to add/remove what ever you want to the code if you wanna see a live preview pls feel free to add me
I understand that due to the privacy of your clients you wouldn't want to link the live versions publicly but you should just deploy the preview on some random server so your potential clients can get a glimpse of what's being offered.
Hey my dms here and on discord are open, you are right about having a demo ill set it up one, in case you have further question let me know
