Here's a great way to make lots of money quickly. Start a new game on 24/7 Mode with a created wrestler. He doesn't even have to be any good. On the Calendar, scroll down to Wrestlemania PPV and select it. Choose to simulate each and every match to this date. It will take a while, but at the end of simulation, you will have made hundreds of thousands of dollars. You can use this to buy new, better character (and other stuff), and you can repeat this process as many times as you want.
