However, I have recently been approached by an outwardly pagan non-profit organization whose sole purpose is conducting a local-area pagan festival once per year.  And while my services will not directly promote said festive and/or the organization's beliefs, there exists the possibility that I could be publicly associated with the organization itself through my services. In that regard, is it ethical for me to take on this client?

However, I have recently been approached by an outwardly pagan non-profit organization whose sole purpose is conducting a local-area pagan festival once per year.  

I am self-employed and provide my services to individuals and small businesses.  In the past, I have had people from all walks of life as clients, including Catholics, Protestants, Atheists, Jєωs, Muslims, etc.  That some are non-Catholic has never been an issue because neither my services nor their business touched on anything that in and of itself could be considered as scandalous.  However, I have recently been approached by an outwardly pagan non-profit organization whose sole purpose is conducting a local-area pagan festival once per year.  And while my services will not directly promote said festive and/or the organization's beliefs, there exists the possibility that I could be publicly associated with the organization itself through my services. In that regard, is it ethical for me to take on this client?  Would it be scandalous if I were in any way associated with this client? The amount of money involved in my services is not what I would call substantial (more than likely, less than $1000), so I could decline working with the organization without any dire financial consequences to myself.  But then again, when one is self-employed, every dollar counts.

What type of pagan organization is this and what exactly do they want you to do?
