Lmao. That attitude, for a start, is what's going to eventually lead to your failure.
Second, investing in a script, which by the way is your core/foundation of the entire project, would be a wise option for anyone serious about it in the long term. Free script? Nulled script? They're never secure. Nulled scripts have flaws in them, most of the time, if not all. Free scripts don't come with a guarantee that they'll be consistently updated with new features and/or security patches.
So, how about you do your homework before you jump in, screw people, and pack up? Figure we all could do with one less failure, don't you think so?
