Is it possible or even feasible to start Neo4j HA with one master and add slave in high traffic time with some sort of load balancing?

From Neo4j Doc :

Neo4j HA requires a quorum in order to serve write load. What this means is that a strict majority of the servers in the cluster need to be online in order for the cluster to accept write operations.

Is one master with no slave available, yet can create a quorum?

If you only have a master then you have no HA. You're just not resilient to failovers. If you have a master/slave setup then as John mentioned you can run an Arbiter instance that is just used to determine the coordinator based on the quorum. To answer your question, I think you'd need to have a Powershell script that would create a neo4j.properties and neo4j-server.properties file on a new server, copy over the necessary files, and start the service. You'll also need a way to poll the HA cluster in order to get all participating servers in order to create the properties files.
