Fix website hack (mobile redirect)

A wordpress website I manage has been hacked and all mobile traffic routes to porn sites. I require a wordpress/webdeveloper who has experience in removing hacked code to remove this redirect. The successful applicant will need to backup all files, themes, databases etc before solving the problem and remove the malicious code. Once the redirect is removed I would like to a report on the vulnerabilities of the install and hope to know where the breach originated from. I will supply both cpanel & ftp/wordpress admin credentials once the job is started. The applicant must be ready to start straight away. Please state you're availability in this regard in your cover letter so I know you have read and understand this requirment.
