Enterprise edition License information

We want to use Neo4j for one of our project.
We want to know if we have own production servers and want to install Neo4j on production server, should we go with Enterprise edition ?
(I read that Enterprise edition has more advantage than community edition if data grows and suitable for commercial projects within an Organization)
If we go with Enterprise edition where we can download free Licensed Enterprise edition ?
If there is any cost incurred what are the breakups ?

@deepahkharishd this was also emailed into support@neo4j.com and will be addressed through there

Hello Team
Sorry. But i haven't got any mail with solution details. I still don't have clear picture about Enterprise edition which we can use at Organization level for production db. It would be helpful if details are shared to progress further for our development.

Thanks in advance.
