It seems like a mid sized Midwestern city could fit the bill. Grand Rapids, MI or Des Moines, IA both seem like good fits to me. (Colleges, low unemployment, spacious to support growth, ripe for more tech companies) I base this off the thought to "help the city". So a large Midwestern city (Chicago/Indianapolis/St Louis/Kansas City) would see little impact from as few as 50 workers. Likewise in a West Coast city with Bay Area expats. And East Coast with abundance of Gov't Contractor tech jobs. I don't know the South as well so can't speak to any good candidates there. Also am biased towards the Midwest.
