TL:DR You will have an incredible experience, beautiful flowers, and Olivia will stick to your budget. Would absolutely hire her again and will recommend her to everyone I know.
Wow! I cannot say enough nice things about Olivia. From day one, she was so kind, patient, and accommodating with everything. I didn't have a clear vision when I first spoke to her, but she was able to take what I knew I liked and run with it. I was planning this wedding from abroad, and she was also so willing to navigate the time difference.
I spoke to a few florists with an initial inquiry and budget, and the first two came back with quotes at least £200 over what I said. I even specified that I just wanted to know what I could get within my budget and that I didn't need to have everything if it didn't fit. So, when I contacted Olivia, I actually quoted her £200 less than the budget thinking she would do the same thing, but she didn't! She told me what I could get within the lower budget I gave her, with a few options for more expensive/bigger arrangements IF I wanted them. I immediately knew that I wanted to work with her, and I ended up getting everything within my actual budget!
Not only is her customer service impeccable, but the flowers were beyond what I ever dreamed. I gave her minimal guidance: not a perfectly spherical bouquet but a bit more freeform, lots of greenery with mostly white flowers, lavender and ivy if possible, and I left the rest with her. I was truly blown away when I saw the flowers for the first time. She put so much care into every detail and the quality was unbelievable. I really can't recommend her highly enough.
I'll include some pictures. I loved that the buttonholes were all unique, and while I don't have any pictures that capture it well, the fireplace and table arrangements were incredible!
