What speed is normal for you?
What upload per month is normal for you?
Making photo is not my job, just a hobby. After work in the evening I upload photos to Dreamstime, not all of these photos are accepted by checkers.
20 uploaded photos per month is my comfortable speed. I upload photos not only for money but also for fun and pleasure. And I enjoy all the process - from making photo till the sale!
