Mickey,
The builds are all over the country and you pick the ones you are interested in. The typical commitment for a build is 2 weeks but we know folks who could only do one week. Other than that there is no commitment. HfH will want to do a background check on you at their cost. We do a build twice a year usually Dade City FL and one other. This is the current build page -
