Hi, @colinodden! Welcome to the forum! 
The team would need a software engineer to install a system and maintain it. To create/update dictionaries, the team would need a data scientist. For data submission, you would need data submitters. The load for these roles can change over time. On the initial step, a software engineer would set up the system. When it is ready, a data scientist will create a dictionary, and a software engineer would assist in putting it to the system (roll the system) on every iteration. Later data submitters would submit data; depending on a volume, it might be one or several people, and dictionary creator could also be involved in this process. A project manager can help to make this process more organized.
Also, there are expenses for hosting and serving data. You might find it useful to check Amazon Web Services calculator or Google Cloud Platform calculator for a rough estimate.
