Shops in las Vegas that you can hire a wedding dress & tux, get your hair done and has a chapel connected?

Me and my partner are going to las Vegas (from the uk) to get married. We want it as hassle free as possible. Which shops do a 'total' everything covered type service? I'd like to hire both dress and tux, and get married at the same place if poss. Hair/make up not such a big deal, but would be good. Thanks for any advice.
