Website Code Clean up

Project Description:
I have 4 websites, the have been bugged with a virus. there hosting provider technical team removed the Malware as soon as it attacked the server. They have advice me to do a thorough cleaning of all websites codes.

2 of the joomla site are displaying on browser but not displaying well. need to either clean up or re-install a fresh joomla and implement the design and theme on old website.

the other 2 website are displaying:
Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING in /home/content/52/8974152/html/ {website name} /system/core/Autoloader.php on line 152

Parse error: syntax error, unexpected ';' in /home/content/52/8974152/html/{website name}/system/application/libraries/Loader.php on line 930

Looking for an expert Virus/Malware and security expert that is well versed in extracting malware and virus injections in codes.
You will need to do a thorough cleaning and fix the codes that seems to be bugged and flush out the injections. You will have to take down the website, clean them up, deliver a working website and diagnostic report.

Then upload clean files to a new server with the database, same hosting provider but on a different dedicated server.

Only quote if you have done similar project before.

I dont want any time-waster, I will give you website URL's in private messages.

Your bid should be broken down into two, 1 for the joomla , 2 for other sites.
