Hacked WordPress cleanup

Hello,

One of my multisite installs was infected with an exploit due to the Revolution Slider plugin that came bundled with one of the themes I had uploaded, and it wrecked havoc because I’ve tried to clean up 4 times and they keep overwriting some of the files on the server. I dont know what else to try.

So, I’d like to ask the community if anyone knows of any reliable service from people who can clean up my install? I guess its time to pay someone who knows how to clean up this mess, I just dont know of any sites that could offer this service (WP specific).

Thanks.
