For investigating feasibility and beginning to develop out the infrastructure, the staging infrastructure alone could keep us going for a few months, at which point we could re-evaluate, so estimated $224/month for that period.
Total staging + production, estimated at $973/month.
Heroku costs are all pay as you go, with (I think?) no pre-pay discounts. Some resources can be turned on and off and any time and are billed by the minute, can even be turned off at night or whatever to save money, although that takes some extra work. (Definitely applies to dynos, does not really apply to postgres realistically, not sure about solr or redis).
