If you start an indoor range/shop, the only way to be profitable is to sell memberships (month or year). Around here in middle TN, a year is going for $200 for 1 person and family for $350.
If you are in a rural area, offer your range free of charge to the local PD or sherrifs dept. Most rural LEO agency's have outdoor ranges or have to drive 2 hours to qualify/practice, and the goodwill will go for miles.
Also rent out for CCW classes or offer them yourself. Evenings and weekends are the best public times, and weekday mornings is good for a womes class.
Become "the name" for high quality merchandise and offer to order anything an LEO might want, even if you make only a small profit.
A company called [url]www.BulletTrap.com[/url] makes some of the finest indoor raqnge systems.
Somewhere there is a DIY checklist for range ownership. If I come across it I'll let you know.
Finally, If you are going to relocate from GA to OR, I'd investigate very carefully the swing of the political pendulum. Noting like sinking 50K into a project only to watch it go down the tubes.
Good Luck
