Depends on how big the jackpot is.
Now if it was 1 billion and I was the sole winner, I'd hire an agent definitely. I would not try and fund the whole project myself, seems like a nightmare, but I'd definitely be interested in getting a good agent and nosing my way into the industry.
Any amount less than a billion, I'm just going to get myself a home, have all my expenses paid for, and just keep on doing what I've been doing.
