Can ministry

Be your "entrepreneur" self employed business? There's someone online who bought a mansion over a million dollars and has all kinds of posts that clearly show the money they have. The couple truly seem like devout Christians. They hold conferences that rake at least $17,000. Have groups that you can join for a fee. Coaching $2,000 a person. Platinum package for event $1200.00... A 3 day speaking event. What are your thoughts as ministry being your business? I'm not taking about a normal pastor's salary but above and beyond that.
