It's always a though call to make.
I'd say if you have enough money to live off for a few months, especially if your wife has a job, it might be worth trying. But if you live 100% paycheck to paycheck, then you might want to wait until you save a little cash.
Don't go overboard with advertising, it's expensive and only marginally effective. A lot of times you end up working to pay for the ads. Just let everyone you know, know that you are on you on, especially old customers. They will be your best source for work. Don't promise work you can't deliver. Good Luck.
