The documentation provided a short, I had to think a little 😬), but in general it is normal.
As part of my task, high-level professionalism - carefully insighted into the task, me to clarify a number of points from which the product was better than I thought.
Be careful about contact, almost always on contact in Skype.
The cost I bet a small, the freelancer did not require an increase, did everything in good faith, although during the discussion the complexity of the task was slightly increased.
I did not set the deadlines. The freelancer did not delay, as soon as new details were revealed, he worked out.
I recommend it.
