Requires a php programmer to refine the site

Good time!

Looking for a programmer on a php, preferably familiar with the Osclass system (message board)
You can read the system here:
osclass.pro/
The system is not complicated, it looks a bit like Wordpress estimated.

Task:
You need to do more on the ad filter on the site working on this system.
Example of the site: eva.osclass-pro.ru/index....
This is shown the full analogue of the site. The pattern is used the same.

There is a detailed TK to perform the task and the working site sends on request interested.

We work on the basis of an hour of work and time spent on the task in order to eliminate problems with the initial assessment. How much time was spent - in accordance with the payment. To do this, the responses indicate the cost of your hour of work for orientation.

This is not one task on the site, but the most important at the moment.

Thank you for your attention.

Waiting for your feedback,
Dear programmers!
