Logo for flower shop needed

I own a flower shop celebrating our 40th year this year. I have just recently updated my image, with a brand new showroom, new trendy products for sale, etc. I need an eye catching logo to match that new image. My business name is "House of Flowers", but contrary to my name, I am not located in a building that even remotely resembles a house...so do not focus on the literal name. I have used hot colors in my new showroom and I'd like to see designs with those incorporated if possible...bright golden yellow, terra cotta, lime green, purple, and black. I do not want a busy design...something simple, yet modern and easily identifiable. Since my logo will eventually go on my delivery van and on my signage on the road front, again, simplicity is key, as people viewing it will be traveling over 45 mph. And of course, it will be used on my website. I used to be a shop that tried to display "class" at all times...now I want to show my area that I am "trendy" and "modern". You know...something Gen X and Y will appreciate.
