A string quartet and a singer

I would like the string quartet and the singer to perform "Buy Me A Rose" Luther Vandross, for our wedding anniversary, at my wife's flat in Silverdale. I have to be out of the country. My wife and I are having relationship problems. I want to show her that I love her and that I remember the song she told me about in March. At the end of the song, I would like the singer to present a bouquet of roses. My wife is a big fan of acoustic guitar, the viola, and the cello, so if we can work in one or more of these instruments, that would be excellent.
