Bigcommerce Template Customization

I need to customize my bigcommerce template. I have 2 websites that are running on Big Commerce. I need to edit the header to have scrolling javascript images and change the background colors along with the left and right side box colors. I do have the layouts for both sites that I originally made for magento. so these can be sliced and integrated. I also want to have the facebook widget to have the same box on the left or right. Please send me sites in bigcommerce that you have designed or fixed. I will only consider people that have actually experience with Bigcommerce. I need this to be done asap. I have attached the layouts that I previously used and will need to edit some of this but pretty much is going to stay the same. Please pm me for any questions.
