Thank you for the opportunity. I can install a industry standard free SSL certificate system (Let's Encrypt) on your server that will automatically renew each domain - I use it on all my websites. If you've already made a commercial SSL purchase, I can install that too.
My background
I have over ten years of experience working on and maintaining websites, from complex to simple one page sites. I have references available if needed from people on and off of Freelancer that I've worked with.
