Thanks for updating the thread.
I checked the licence manager and can that one of the website is not working. While the other is is using fairly old version of X Theme. Looks like on that website, Cornerstone is not active.
First, I would suggest you to update X Theme and install Cornerstone. You can take a look at following resources to get started.
That being said, if you could elaborate a bit more on the inputs that you are looking from us, we can try to assist you better.
If you are looking for professional help, I suggest you to post the requirement on Facebook group and Themeco Peer to Peer section. I am sure you will get good response from there.
