the adequate cost of solving the task,
Minimum time of execution,
constant contact with the executive,
- the optimal making changes according to your wishes in the task is for you to this guy. He was sitting with me for three hours on the tube. Even when I dropped for an hour and I urgently needed his answer - he was here as here. The task was understood by the East, and what was needed - he asked, not shameful. At the same time, the task was non-trivial, and obviously not for the middle minds. All the originals dropped. I'm in a pleasant shock that my project was decided in an hour, and I've got a free deposit! If you have a share of this freelancer in the task, then the minimum that you have to do is to write in the face and discuss details, and to those who have not done it, I’m very compassionate)
