Money is necessary to keep you alive and on your feet. Especially you who as I've seen had financial and environmental issues in the past (or even now), you really do need to accept payment for your services.
It's great to give back to the community like this and enrich it with your work (which I quite enjoy myself by the way), but you shouldn't try to do it for free.
Here in Satanism, all our work for the community is rewarded one way or another. There is always "payment" of some kind. A way that the community gives back to you for what you do. Please do not feel bad about accepting these payments from our community for your services.
Our Astrologers here don't offer their services for free either. Their time and effort is paid for with money, so that they can continue doing what they do.
