Hello,
I do understand what AMP is and already worked on a real estate website. I can show you if you ask in "chat".
About your project, as you mentioned, there are only 2 files which needs to be updated and you wanted the bid for ONE template only, so here is my bid.
Still, before any confirmation, I'd like to see your existing website/webpages. If any discussion needed, we'll discuss that in advance before starting the project.
Let me know.
Regards,
Anurag.
