Live Music for wedding?

Hey girls,

I am having a small reception/dinner and was wondering if you guys know a small band who would play songs during dinner. No dance floor so it will be only love songs for me and FH to dance once or twice.

Also, it would be nice to have smooth and nice live music (maybe violin and piano keyboard??) as a background music. I guess no singer will be necessary just an instrument or two. How much do you think it would cost and do you have any suggestions?

Thanks!
