In the end, the final budget was a couple hundred less than the planned budget due to not needing to buy a gimbal; needing as much money for the costume and mask; and not buying a final batch of custom USB Drives. However, I had not accounted for transportation and with filming in four different boroughs, going upstate, location scouting, and traveling to even have meetings meant a significant amount of money was spent on travel. I think even if I had made an estimate for transportation before the start of the project, we would have eclipsed it. I know now to definitely meticulously keep track of the cost of travel as well on any future projects.
