If I buy a vacant land and I need to put electricity and water on, how much would it approximately cost?

Would it be better to buy a already build house or to buy a vacant land and build your own house?

what is the cheapest price one can expect to pay when building?

And what should I keep in mind when deciding to build?

Sorry for all the questions, but it is quite urgent and I really need to know which one would be best?

Thank you in advance
