Am I ready for a baby?

I just turned 30 and have been married for 6 years. We have never tried to have a baby yet, but I have been thinking about it a lot lately. All of my family lives in another state and I have no support system out here. I have a good job, but it doesnt full my need. I really would like to move closer to my family but that means changing my whole world. anyone else ever had a similiar situation? thanks for the advice.
