Absolutely not recommended. I strongly advise against investing your money or time in this script. I have been working with classified portals for over 20 years, and while such a script might have been acceptable 15 years ago, it is completely outdated today. The handling of images, thumbnails, and SEO is poorly implemented, full of bugs, and even the demo version performs very poorly in Google PageSpeed Insights https://utn.pl/hYQTj
These are the absolute basics for any modern application and for any developer who takes their work seriously.
