Cleaning and migration of 3 websites, from Bluehost to VPS URGENT

I have a hosting on Bluehost that is infected with malware, on this hosting I have around more than 50 websites, but I want to focus on 3 specific websites, I want these sites to be cleaned and migrated to a VPS that I have with another provider , we look for efficient methods that guarantee 100% security that no malware will be transferred to the vps, we seek to be aware of the process and know the methodologies applied, therefore we hope that these 3 websites are completely free of malware at the time they arrive at the new VPS, both the cleaning and the migration is what we are looking for the job.
