I am a game developer and I can tell you it will cost upwards of about $20,000 for a game like that. It's not just building a structure, you have graphics, admin panels, couple dozen DB tables, hosting, server, and many weeks of coding.
However if you do it all yourself, it's free.
I suggest learning some languages and build half of it yourself, and hire someone to fix your mistakes and to finish it. That way you can walk away paying around $7,000.
You will be dealing with more than 100 files, and at least 200 functions.
