Greetings,
I'm a linux specialist, in the ISP business for over 15 years now. For more information about me, please take a look at my profile and feedback, that the best reference I can offer.
Working as a hosting provider admin, it's quite common to stumble upon infected sites. I can handle your request, clean and secure the site(s)/server in case this is a Linux installation for the price bid. I'd need SSH access to the server for this.
Take care,
Istvan
