Malware at wordpress

I'm looking for a freelancer with experience in malware removal to help me with a problem in my WordPress website. The source of the malware appears to be a WordPress plugin and I'm not sure which type it is. I'd like the freelancer to do a thorough analysis of my site and help me remove any malicious code they find. The ideal freelancer will have past experience that they can demonstrate and present a detailed project proposal with their application.
