^^ This. Forums are very helpful in many aspects (I look for advices too all the time), but I'd suggest to talk to local folks with knowledge (barn owners, or simply people who keep horses at home): what kind of hay is in your area (personally I do NOT feed alfalfa as it's too rich, everyone I know goes with grass hay (timothy, orchard, brome, or mix around here)), recommended suppliers, etc.
I also keep salt block in a field, and both my mares get pound of low-sugar pellets mixed with vit/min and flax twice/day.
