Do not underestimate the time it takes for you to program anything. like a game... for one person with basic HTML it takes many years, even when you spend 6 hours a day.
Think about: the functions you need (more than 1.000 for a good application, UML-diagrams, database-structure, frontend and backend work, security, auditting, a framework (not the div's in this case) to build all the functions.... All of this, you can't learn it in a year... Maybe 2 years...
You get it?
