Reverse Proxy Setup

Hey there, am not a developer or i have least knowledge about it. But am in very bad need, i want to mirror the "[login to view URL]" in my blog. But as google had blocked the x-frame options for cross origin domains, so i can't do it by the iframe. I googled it and found "reverse proxy" by which we can project the others website in our website. I knew one developer and he installed via reverse proxy on ngnix but its not working fine, he installed reverse proxy of [login to view URL] on "[login to view URL]". And i want to mirror the [login to view URL] in [login to view URL] which is the actual blog via iframe. But when am inserting the iframe of [login to view URL] in [login to view URL] (although same origin) its not loading. Moreover [login to view URL] is not working fine on mobile version (for desktop version its good), dynamic content not loading on clicking. So i would like to know the proper way of installing reverse proxy or vice versa way to project the [login to view URL] in my travel blog. Am ready to pay the developer if he can able to address the issue and successful install it and makes it working fine.
