How established should I be before dating.

How established should I (30m) be before truing to dating, especially if I want something long-term? How much should my income be? Does it matter what the source of my income is? How much should I have in savings?

At the moment, I've got a few shifts as a kitchen hand and make a bit above minimum wage. I have a degree, but I'm having trouble getting work with it at the moment. I could consider learning a trade or something?
