Need a homepage design for Hydroponics site

Hydroponics America

The owner of the company is entering the hydroponics e-commerce field after many years in hi-tech marketing so they're used to slick eye catching designs and we're looking for something that will visually set us apart from the competition.

Home growers who need hydroponic supplies (indoor gardening). Some of these growers range from new to very experienced - we need to help them find what they are looking for easily and help them navigate through potentially thousands of products.

Please use the proposed layout (ha-final.jpg). Slight modifications to the logo are okay if necessary. The challenge is working with the logo and it's elements within the site.

Color palette: warmer colors preferred, something bright and engaging is fine. The site is selling indoor gardening products so keeping with the theme is fine.

The landing page is made up of the following areas:
1. Feature space : three rotating features with big graphic/photo
2. Product category grid directly below the feature space. For the comp, please use the images in the layout space and use appropriate labels for the category.
3. left hand nav - list of product categories
4. right hand nav - popular products will include product photos and prices.

We're only looking for the landing page to establish the overall look and feel of the site. Once a winner is selected, we'll engage with the winner for additional pages and comps at a rate to be negotiated.
