Need help with calculation of estimated price per month

Hi, on the current moment, I use FlightStats API fo the same needs that I will use your API.
Can you help me calculate estimated price per month with your service using next I have:

  1. Expecting verification of flights using AirlineFlightSchedules of V3 API - 330 000 requests/month
  2. Expecting SetAlert V2 API - 350 000 requests/month
  3. Expecting PushAlert V2 API - 11 760 000 responses/month (where 28 push per flight as median value)

When I trying to calculate approximate price per month I have next:

  1. V3 - regular price 1000$ after beta
  2. SetAlert V2 - 350 000 (requests) * 0,00030 (per call) = 105$
  3. PushAlert V2 - 11 760 000 (pushes) * 0,00130 (per call) = 15 288$ (I get this value 0,00130 as multiplier because do not know Contract plan cost)

Estimated total = 1000$ + 105$ + 15 288$ = 16 393$ per month

Can you verify this and correct me if I wrong?
