R&B Soul Jazz Singer

Hi, I am looking for a great R&B Jazz Soul type singer that can really capture the hearts of my guest, get them to snap their fingers and feel good. I like this music so much and looking for someone that can do my ceremony and reception. Any suggestions? The list here are frustrating because there just a bunch of names and I want to see them and hear them and know they are awesome before I hire them. Thanks, Carrie Ann
