Modify Opengraph Meta Tags for WordPress

I can almost program this myself -- however, my programming is only 80% good enough. I would rather pay someone else to do it. Plus, I am very busy and don't have the time. So, again, it's better to pay for help, as I would like this made as soon as possible. I believe there is about 8 hours work here. MY SITUATION: I have a functional, live buddypress installation in WordPress using the KLEO theme. I want to generate different opengraph meta tags depending on which URL is being shared to social media. If the URL is: ---1: Someones profile page, their cover photo should become the opengraph photo. ---2: A status (or group) post, The photo in the status should become the opengraph photo ..OR, if there is a YouTube video, the YouTube video thumb. ..OR, if there's neither, FreedomWorkshops default opengraph photo should be used. ---3: A forum post, The photo in the post should become the opengraph photo ..OR, if there is a YouTube video, the YouTube video thumb. ..OR, if there's neither, FreedomWorkshops default opengraph photo should be used. The METHOD: I do not want to start modifying programming and plugins, etc. It's too much trouble. So, the php written will load the html of the page (or use current information in the meta tags) and extract the information that way. Then, we will use that php to echo opengraph code into the html header. Or, if there's any other way to accomplish what I want, without modifying existing plugins, I am open to suggestions. But if I were to program it, I would get the information out of the rendered html. But then again, I am not a very good programmer. I still have some things to learn. Maybe you know better. I have a php file that is included into the header. I wrote this file. It basically handles a few session and cookie variables for a referal plugin. So, I would like to add more code to that file, which is in the WorPress [login to view URL] For "1" the php should detect if this is someones profile page and put the header photo in. This is the most simple. For "2" the php should use the users cover photo. However, if there is a YouTube video detected, it should take the ID of the first YouTube video and get the thumbnail from that video via the YouTuber API. For "3 it will use the exact programming as "2".
