Customize bigcommerce themed website, create graphics

I am going to build an ecommerce store using BigCommerce and one of their templates. I need you to design it for me. It is going to need a custom logo and a header graphic to make the store look nice and custom. It is a girl themed page, so the colors will be along the lines of pink, purple, and white. I need a custom homepage with an outlined text section at the top explaining the store and how to order our product, and then below it will be 3 or 4 of our featured products outlined in boxes, with a choose this one button. The order flow of our product works like this: Step 1 for the customers will be selecting a main product. Step 2 is they should be able to select which features they would like on the main product. Then step 3 is selecting any additional accessories to go along with the product. Step 4 is checking out. We can enter the products, but you must make a nice custom girly design and have it operate using the product flow I mentioned. If you need more information, please ask. If you are unsure of something, please ask before bidding so you can bid the correct amount for the work required.
