My gifts come from the Spirit, so with that in mind, I "sell" them for money but I call it a suggested donation because if someone does not have the money to pay me, I will take trades or work on a sliding-scale or lower my prices. I believe this is the right thing to do. God is my Employer. He provides what I need as long as I stick close to Him and perform His work well. Therefore, I am flexible with regard to prices.
