I'm sorry, I'm going to be completely blunt here. I looked at your gallery on your website and I would suggest you get some schooling and hopefully some refrigeration. I did notice in your photos, flowers that looked "old" or having been subjected to warmer temperatures which impair the longevity.
I am not perfect, but I find your designs lacking in some basic principles of design. I highly suggest you invest some $$ and energy into some hands on classes in your area. I wish you the best.....if it is what you love, pursue to be the best.
