Look for a small/mid size local bank that specializes in this, they will detail what you need, survey, building permit, architectural plans and a builder contracted for starters.Or when you're ready to subdivide/redevelop you just sell to a builder and have them split the lots and transfer title to you for your smaller lot, he keeps the others and let him mess with the utilities and building.
