Flower advice...

hi ladies, i need some flower advice..i got a quote for about $3,500 for 12 centerpieces (high candelabras, about 33 inches, with black magic roses) and candles, my bouquet which will be black magic roses with eggplant calla lilys, two bridesmaids bo-k's, groom boutenniere along with two groomsmen boutennieres, and a card table (which will have a tree with tealights and hanging crystals)...im wondering if i jumped the gun, is this a good price or should i keep looking? Technically i said yes to this package but have yet to see my sample..and i havent signed a contract!

good deal??
