We just booked ours this weekend, she is a judge. Her fee is $100.00, $150.00 if we want a rehearsal. I had contacted others, and noticed their fees were all higher, $200.00- $400.00. Maybe, contact your venue, and have them send you a list of JP's they recommend, that's how we found ours!
The pastor I used was $150.00 which included a $75 janitorial fee, but then I also gave him a gift & extra donation to the church. So all in all I think I spent $300
