Artificial flowers

Hi all, is anyone else doing silk flowers? I'm going for a Marie Antoinette look, and I only want two really extravagant, flowing flower arrangements at the two ends of the table (we'll have one long table for all the guests), then the smaller table arrangements will actually be fruit and greenery - grapes, artichokes and pomegranates, plus groups of candles. I am kind of blown away by how pretty the test flowers I got are, and what you see here is around 60 euros worth. I'm guessing with the extra arrangements (arch, stairs, buffet table) I should land at 600 in total for a big abundance of flowers - and since we are buying/collecting most of the things for the 70-people wedding at antique stores (plates, cutlery, table cloths, chairs), my mom was thinking we could try to rent everything afterwards.
