Hi, I would love to help you with this and will be able to turn the work around quickly. Presuming your site is Wordpress I can help you. I've set up open graph tags on my own site Lifetime Backpacker, and many clients during my agency role.
Open graph is great for dictating what images and information you want to share through social media when a link is shared, so I can understand why you need to implement.
Get in touch and let's get this sorted out for you.
