So, after getting ordained in college I have performed ~10 weddings for friends and family over the past couple of decades. I've never set a fee (give me what you want if you want) and I have two basic requirements:
1) Have real premarital counseling. It can be with me, or it can be with a degreed counselor. Cover the basic conflict points to make sure you're on the same page (money, kids, dealing with in-laws, who works, etc)
2) Provide a script. These have been VASTLY different weddings, from the Cherokee/Celtic blend I co-officiated to the Baptist(ish) one on the beach on Maui.
I've toyed with the idea of doing this as a side gig. Now that MrsTX has a side gig and we're going to be Schedule C anyway - the thought has become more appealing.
I suppose my competitive advantage is being flexible and nontraditional. Are you a gay trangender interracial couple who wants to get married down in a cave? No problem.
However, I have no idea what I should charge. Fancy wedding folks - what's the going rate? Should I offer different "packages?"
I'm also thinking I should drop the first requirement if I'm just doing this for a side gig. For my "free" services, the only marriages that didn't "stick" were the two where I relented (or was outmaneuvered and unwilling to walk away) on the counseling
