You can get a basic home connector for $500. Then just have your electrician pull wire at $500+
Commercial unit that tracks billing and restricts access with a key card is a bit more. Bollard mount alone can be $2,000+. Then you need internet or cellular connection for the billing along with a service agreement. Depending on location and conditions can easily top $10,000 each for the initial set up. I see the actual bills around here. Don't forget ADA accessible if required in your area.
Sometimes I think the home unit and give away the electric is lower cost.
