Hire music students to play the ceremony

If you are inclined on having a live music for the ceremony then consider hiring an amateur or music students. They charge negotiable lesser than the professionals as they are keen for such opportunities to pile up their experience. You can contact music departments of colleges to track the best event players. Or can contact local music teachers who would refer their top students for your event. Asking a family member who is a good musical performer would also save you the cost. You can humbly ask for this favor as a gift from them clearly not taking advantage of them.
