Front Page Redesign

We are moving existing website to a wordpress and woocommerce engine. You can see existing site at www.trinitydiamonds.com. The site gets 65% of the views via mobile so phone number is important to have on top. 90% of the views are local. We are looking for a eCommerce friendly color design using the woocommerce storefront theme with Boutique child theme. The colors should be similar to the existing site. The requirement will be to come up with a header image (1950x400) and the colors (#8883a0) that work down the sides with that image. Need to have our trademarked slogan in the image. (Your Love has a certain Ring to it!) This will also mean you must have some abilities to change themes and the CSS with those themes. Experience in CPG or other jewelry sites would be helpful. All changes to the theme must continue to keep mobile friendliness. Winning person/company will be considered for continued work making regular images for promotions and emails. Needs/Requirements: 1) Change Theme to use shorter Header Image 2) Design header image 3) Use existing color, or match a different color to header image 4) Using wireframe that is included, make recommendations on style and colors and additional items that would make the page interesting. Deliver those images/changes with the project.
