Hello Sir,
I am an expert WordPress developer and I'm really interested in your project. I bided with $50 because that's more likely enough for this job.
At first, you mentioned that you're having some problem with the Open Graph(OG) tags. No extra coding will be required for this fix. I'll try with the plugin at first, but if you hate plugins then I also can implement those tags right in your site's theme file.
To remove the "Read more" links there are two ways are available, Editing the theme file and remove it from there, Or we can also hide this using CSS. I can do whichever you preferred.
Other jobs can be done by implementing custom CSS codes.
I've added milestones for every single task. (I'm new here, But I think it'll be helpful for you at some point.)
Thanks, Looking for your reply.
