My best suggestion is to call a local florist in the area you are wanting to send. Not only will you get a great price, without the middle man, but usually a nicer/fuller arrangement. Just tell them how much you want to spend and they will do the best for your budget.
Don't just google either, like "Tampa Flowers" more than likely will bring up a 1-800 florist. Find one with an actual physical address in that town.
