Building a website for “Ashram”

Hello Rabbi, I was asked to build and publish a website that deals with “spiritual” matters (not medicine).
All kinds of spiritual workshops and also different types of treatments, they call it something like an ashram.
In principle, if it’s related to the GAZ, but I don’t think anyone from this company really means it.
They gave me the following website as an example of the style they wanted for a website:
http://www.desertashram.co.il/

Is it permissible to build and publish something like this?
