Oh dear ... tell us your story LOLS. Did he "marry you out of the truth" as in he was brought up in the cult but never got baptised and found you?
He must be thick to become a true believing jw nowadays. (As opposed to one who is going through the motions to keep his family happy.) Please tell us he holds down a job and you don't have kids. PLEASE.
SL and DB above explains what he will soon be able to do.
He will first get used on running a microphone at the kingdom hall. If they are really short handed they might make him an assistant on those departments mentioned in his post above. He might get allowed on the trolley carts if he has "good ministry" after a couple of months.
If "he has the circumstances" he can apply straight away to be an auxiliary pioneer (30 hours a month at certain times of the year, 50 hours at others) and after six months (usually after successfully auxiliary pioneering or having an outstanding ministry) he can apply to be a regular pioneer where he will be expected to do 70 hours of timewasting err... ministry per month for a year.
After a year he can technically be made a Ministerial Servant if he "qualifies" (10 hours per month of ministry - being seen out knocking doors or cart witnessing, attending meetings regularly and answering up well) but unless they are really desperate it is more likely he will be given a lesser department to run like "sound" or "literature" or "hall" first. It usually takes at least three years of brown nosing and "exemplary" conduct to be a Ministerial Servant.
