one other thing though it is a bit different than mine with the light add on work it like this and enjoy it until you either see people are or are not asking for lights. If its used you might as well either get rid of the lights or include the add on at all events and charge accordingly with only the one package. Mileage may vary but I know many have typically said that when offering those additions the client especially with the current economic times will go without to save a buck. In the end they are hiring you and the personality above almost everything else. Gaining a face to face has made this the easiest part for me.
