Design a Website Mockup

I would like a new website mockup for both the desktop and mobile version of a commodities trading and shipping services company. The site should be user friendly, appealing and attractive. I have the logo so the color scheme of the site should resemble or be based off of the logo and its colors. I also need another website mockup of a construction site that needs to be very clean and simple. If the design is done well, i will offer the development project to you.
