Верстка страниц
Unfortunately, the project has not been completed.
I waited until the last, a month ago was the last promise that will be "to-to-to" fulfilled, and the last 2 weeks there are no answers (although the messages read)
It was not the first time I worked with the artist, but the result was not expected.
I hope that it will fix.

Per, the great multitasking does not allow Denis to regularly and quickly answer the customer’s questions. There is no documentation yet.

Разработать модуль для сайта
The task is half done.The attempts to resolve this issue and the requests to do the project were not overwhelmed.I am constantly writing, calling, and trying to make a project.The executor knows how to do it, but most likely because of the lack of time does not respond to the messages for 5-6 days, and after the answer everything exactly nothing happens.At the beginning everything went clearly and clearly.It seems that the work was done, the contact was instantaneous, and then that was broken.After another 5 days of silence, I close the order with a negative feedback.There was also a touch to the fact that the artist took to write only the program code, and the visual layout is not his question.Although when I put a task, I brought an example of how everything should look like an example of already finished work, where there was visualization.After the application to the arbitration for 5 days, the task is never fulfilled, there is no one letter from the executor, although it goes on permanently.I’m not going to pass on the person because I don’t know the reasons for this behavior.I really wanted to solve the question normally, but it was really tired to talk and wait not knowing what.
