Mocha - out of curiousity, what are you charging for these cylinders may I ask? What kind of labor do you anticipate in prep and on site? My brides are pretty traditional and it's one floral centerpiece after another. This is unchartered water (sorry for the pun) for me...
Sorry, I must have missed this when you posted. These are a fairly affordable centerpiece for the most part since they are only using 1-3 stems and rent the vases.
When I price them, I charge a rental for the vase, stones, et.
Then I do a 3.5-5x (5x for cheaper flowers and 3.5x for pricey options like cyms) markup on the flower and add 40-50% labor on the arrangement. This is to accommodate the extra labor on site. Depending on the site, there may also be additional set up charges if we have limited time/ resources and have to bring in more people.
Oh and the 2.5 markup on candles, wire, etc.
Like I said, I've done more of these than I'd like so they are somewhat of a science to me. Next 4 weddings on the books are all submerged...
