How much money would it take to start a homeless shelter?

Gods plan for me is to start a homeless shelter where it will not just be a temporary place for them but a stepping stone. Where they can get job training and assistance in looking for housing. I just don't know where to start. First I wanted to know how much money you think it would take to get it started? I am looking for an abandon church as the building and I will get a van to pick up homeless once I have it ready and take them there.
