Just start a colony of about 50 in a Sterilite or Glad tub. Not even a real need for a top. Give them egg crates and food then let them do the work. Feed them cereals and cricket gutload if you want. Also I have found that feeding them fruit...carrots and oranges promotes breeding and keeps them hydrated. It took me about 2 or 3 months before I saw any babies. It is very simple.
