efficiently, efficiently and according to TZ. Thank you for work!

The bone completed everything in time, quickly and affordable, without missing for a few days (who communicated with freelancers - will understand). He fixed all the faults of the design and added what we forgot to take into account at all stages. I understood my blond tongue (“this button to press and this line to wash out”) and I did everything right! He has exhausted TZ without hysterics and khanchism. A huge thanks! I hope we will open up and order a more advanced website and application. Now only you!

I had the first blin always a com and this service is not an exception, the first freelancer whom I chose with a cloud rating (by the way) me deceived said that it will make the site under the key 100%, instead began to cook the cushion from the top, and here you are here to me and that and that I don't know that you want. Good that there are exceptions and the bone of that confirmation, I was given, corrected the curve site, the prices are most democratic. Thank you very much, Costa. I recommend it!!The !
