Richard, I think you understood the graph data model well enough to get started, I recommend to take the online intro course to get up to speed with the query language.
it should be easy to get your data imported into Neo4j with LOAD CSV + MERGE for hosting there are cloud hosting offerings for neo4j, your database could even fit on one of their free plans see: http://neo4j.com/developer/guide-cloud-deployment Not sure how you would connect to the database from an application or if you just want to use the plain database for your own or department/school use?
