Anxious for new website

Designer sent me information of website layout. I think it is looking great.It has taken a lot of planning and what a hard decision is to pick something mundane as colors. I think I have read and looked at every color diagram out there and read the psychology of colors, whats hot and whats not. Some of details being worked on right now is categories to list on site, writing Privacy Policy and adding a dozen scripts to the page. It has to be right the first time. There is no second chances at the online game. Get it right or fold the tent.
