I'm looking for recommendations for a good website builder using php. I want to build a professional looking website for my business, and would like to use open source tools for obvious reasons. The tool must be very simple to use, and offer a lot of templates that allow me to just fill in the content without any coding. And, I should be able to create drop-down menus on mouseover, again without coding. The site is mostly content based and fairly simple for now, but would include a bunch of forms in future and I plan to have a php developer doing that stuff then.
I will appreciate any suggestions. Thanks in advance
