Hi there,
I can add h2ml2canvas to your website. I am a professional system administrator, and also a pro web developer so have the perfect skill set for your job.
I can also make you a video to show you how I added it, to help you, should you need to reimplement it in future so you do not need to pay again to re-implement it, and can instead complete the work yourself.
Please see my profile if you would like to read what others think of my work, everyone I have worked with has rated my work as 5*'s and many said I was the best freelancer they worked with. I work hard for every client I work with, and treat every project with great attention to detail and care.
Best,
Gary
