I HAVE IT
Good day!
I took a look at the link you provided and I saw the theme you want to purchase.
From what I understand, you want to watch it live and well customized on a website, so that you decide if it's the right theme for you.
Frankly, I don't have it and I have never purchased it. But I can guaranty you that I will make it look exactly like the "live preview" (demo) because I am a WordPress Developer (Theme/Plugin) with more than 4 years of experience in Front-end Web Development (HTML, CSS, JavaScript, PHP, and Bootstrap framework, etc).
Please feel free to contact me, if you need more details about my approach.
Thank you for this opportunity; I hope to speak with you soon.
