Question asking for a software with such specific elements and business rules, like the one asked by @Chris where he ask for tours booking portal.
That is one Portal (as himself states), with specific rules and requirements. in my opinion this is as @James said in his comment:
Yeah I have to agree, this isn't an application, this is a full system with many apps...this is a company potentially – James
And also as @danijelc said:
This kind of software are usually build from scratch.. Since most of such operational software have really specific requirements – danijelc
We are not a SE for Freelancing projects. And this looks like a software for a company to build, since this need very specific requirements and business rules. With customer personal needs.
I flagged (since I can't vote yet) for the closure of the question as "
too broad", because I couldn't find a better way to explain this.
I even checked on meta and only could find the question Custom close reasons for software recommendations to help me with the option of the close vote.
