Long Island Musicians Classifieds

I am 25F looking to sing with a band. I love to sing and just want the chance to get heard and see what I can make of myself but I dont really know where to start. I've sung solo, duets and with groups formally in church and college. I am married and just looking to really do something with my talent. If possible go career. I have been told a thousand times by many people (friends, family and many complete strangers) to do it but I have no clue where or how to start. I sing everything from motown and oldies, to rock, country, folk or party music. I love to listen to the band so I wouldn't be caught dead telling them how to do their thing. Anybody have any ideas? (besides American Idol LOL)
