Relactation help?

I am interested in relactating to help provide breastmilk for my eight month old daughter. Any help would be greatly appreciated. It seems we are always running out of formula right 2-3 days before payday. It sucks!! It's super expensive, too! I'm 100% for lessening the cost needed for it. I dried up when she was 2.5 months old and haven't really produced anything whatsoever since then. Please help! 😞
