CSS is a stylesheet code.
I have stayed away from designing it in Photoshop because I cant cut sites for shit. However, all the additional images etc can be loaded into this from photoshop, this is merely a layout
Well I packed everyone in my house off to bed and decided to dust off my website package and came up with this as a rough idea of something (believe it or not it is actually a website under the influx of colours)
Obviously you would have to use your imagination of what goes where once it is finished with the correct images etc. and the menu bar is adaptable, thats just a coded I have used before
Its adaptable and can put in what you want If you want to head down this route, and believe it or not, the design is already 95% coded.
Let me know what you think
Just a couple of things that I can work on to give you more of an idea
What colour scheme are you after?
What does the business do? is it just lawns or what etc
