If I want to do it legally, then I need to become an energy provider company and keep all bureaucracy and maintenance as an energy provider company. Sorry no, there is a public charger of somebody who already did this leg work.
Some of the public charger networks have offerings to manage that for you. You can task Chargepoint to install and maintain a charging facility on your premises for instance. This way you just need to organise the parking and the access to the connection, but everything else is outsourced.
I could surely also task OMV to build gas station on my property, question is why should I do that?
