Remove malware on site

Good time of day,

Such a task: on our site (wardpress) a lot of malware (malware) which as we understand penetrated the site just through vulnerable plugins. The admin lost the buttons of the update and installation of plug-ins.

We need a wordpress core developer that can remove malicious code, including anything that Google can classify as Malware.

Because you will need access to the site will need to work on my computer (laptop, with good specifications) and with me (in a coffee shop somewhere). Ill pay for the cash to solve the problem. Only Kiev.
