hey cupcakes, share your florist with me on fb can? im also looking for one...
lissy~ i think for venue usually you would need entrance arch (optional), reception table centrepiece, cocktail tables centrepiece (if any), floral stands along the aisle, table centrepieces for VIP table/s and the rest, and stage backdrop decor. you may want to ask them to include price of loose rose petals if you are getting your flower girls to throw / lining the aisle / placing along reception area etc etc (if your venue allows).
of course you may want to ask them for other things as well that perhaps your BS does not provide. for me i need to find a florist to add on other floral stuff like bridesmaids' corsages and bouquets, groomsmen' boutonnieres, candy bar floral decor, flower girls' baskets etc. fyi
if they can give a package price that would be best. (get them to give you the a la carte breakdown and then compare amongst a few florists to make sure you are getting the best deal)
different kinds of flowers have different costs, so choose wisely! haha
