How much does it cost?
oh boy, what a big question, I'll start with the languages first...





Simplified:


HTML is a language used to make websites and stands for HyperText Markup Language.





XTHML is a variation of HTML and stands for Extensible HyperText Markup Language





CSS is Cascading Style Sheets and is a simple mechanism for adding style (e.g. fonts, colors, spacing) to Web documents.





XML stands for Extensible Markup Language and is used to facilitate the sharing of structured data across different information systems, particularly via the Internet.





Javascript is a scripting language most often used for client-side web development. It is a dynamic, weakly typed, prototype-based language with first-class functions.





PHP is a reflective computer programming language originally designed for producing dynamic web pages. PHP is used mainly in server-side scripting. PHP stands for Hypertext Preprocessor.





Perl is most popular dynamic languages for writing Web applications.





Python is a dynamic object-oriented programming language that can be used for many kinds of software development. (cool fact: NASA uses python)





AJAX (Asynchronous JavaScript and XML), or Ajax, is a group of inter-related Web development techniques used for creating interactive Web applications





C# is intended to be a simple, modern, general-purpose, object-oriented programming language.





C++ is a statically typed, free-form, multi-paradigm, usually compiled language supporting procedural programming, data abstraction, object-oriented programming, and generic programming.





Now that all those Big technical words are out of the way, If you know what your doing, you can make a website like google or yahoo for free. It will of course take you a long time if no one else will help you. But if your just interestind in hiring someone to make a big site like that for you, I can't give you exact numbers, but you better be cracking open your piggy bank because sites like google or yahoo are worth about $50 billion dollars.
Reply:If you think about it, those sites are manned, designed and operated by thousands. If you really want something even comparable to those you've identified, it would run you into the millions. Most of the workers employed by these web firms are software developers, designers, test engineers, project managers so you can imagine the amount of money just for salaries.





The languages you listed are a mix of mark up languages and programmatic languages. Go to the search engines and read up.
