If you are not familiar with it, you can get an free account for 14 days no credit card needed.
The page outline is going to be the same as the old site. Don't worry a lot about the constant. I can do that part.
What to avoid
The attached logo is the company logo. The logo need to be used in the new website.
I also uploaded a scan of the brochure as a design idea. I like the flower looking design in it.
