As long as you can get your images geotagged properly and you can break it up into sectors of 2-3000 images it should work fine.
We only provide DSM files and do not get into feature removal for the creation of DTMs. The rest of the file types are offered as seen here:
10000 images a day can be handled in 3-4 separate maps. These can be run concurrently. Each map will likely take a day or two to process. So as long as you start processing the data the day you start collecting it it would be done shortly after.
We don't need to sign anything. This is what the system does. All day every day.
