looking for Freelancer to do website maintenance and security

I am looking for a qualified Freelancer, with expertise in website maintenance and security, to help keep my website up-to-date. Primarily, I need help with fixing broken links and errors, as well as implementing security measures to protect against malware and hacks. The frequency of maintenance can be flexible, generally now and then, but possibly once bi-weekly. I am looking for someone who can be reliable and provide the necessary updates and security plans to make sure my website is current and secure.
