Good evening. I am getting married next spring, and I want to surprise my fiancee by playing our song on the piano during the ceremony. It is a pop song from a few years ago, and I cannot find any decent piano arrangement, only guitar chords. I play at an intermediate level, but I cannot write an arrangement myself. I have about four months to practice. The ceremony will be small, about fifty guests, so no pressure, but I still want it to sound good. Is there a way to get a custom piano arrangement made for a specific song, and how long does it usually take?
