Church Planting

I have had several conversations with some of you guys over the past few months about church planting. Since no one has posted here in a month, this is a good time to. I would like to hear from you on several questions.

1. If you were thinking about church planting, what would you consider when thinking about a location?

2. What steps would you take to prepare for church planting?

3. How long should you take to prepare before being "on site" of the church plant?

4. How should one go about gaining the support of a local church or churches?

These are just a few things that I would love to talk about. Obviously I am thinking through this on a personal level, but I have no idea if this is where God is leading me. So I would like to hear some thoughts for church planters, whether myself or not.
