develop my designs into Big Commerce platform

I have a highly customized design ready, and I'm looking for someone to develop this design into Big Commerce's software platform. The issue is that I want it to appear as if the shopper never leaves my site. Please bid only after looking at the following: The general site is here: [login to view URL] Most of it functional, but some isn't. The section I'm most concerned with is "matcha store." Right now nothing happens when you click on it, but the actual pages are as follows. We have the landing page of the matcha section finished: [login to view URL] When you click matcha store, it takes you here: [login to view URL] Then we're doing individual product pages. [login to view URL] You see how we never leave the look of my website? I want the headers and footers to remain, even when we go through the checkout process. Also, as you can see from looking at the bottom of the matcha landing page, [login to view URL] I'm also selling ceramics, and tea tools. Ceramics include a cup, and a creamer. Tea tools include a whisk, a bamboo scoop, and a mesh sieve. Design work on these pages will finish next week. So I'll be selling eight products total: 3 types of matcha 2 types of ceramics 3 types of tea tools. Please let me know if you can create this EXACT design with Big Commerce. The work should also include: * Mailchimp integration * superior shipping integration * superzoom photo zoom * mobile commerce * sell on Facebook * sell products with options (ceramics come in three glazes/colors) * hyper seo optimized * optimized for QuickBooks integration This ecommerce portion is just a part of my overall site, referenced above Most of the navigation sections work fine, but some will need cleaning up/tweaking. Most importantly is the "matcha store" section: this is where the BigCommerce portion will live. I am hoping this can be done seamlessly. Please give me your opinion on the best way to integrate the ENTIRE site and make it work seamlessly together. Right now most of is static, and the blog runs on Wordpress. So integrating the entire site with the BigCommerce stuff I'm asking you to do would be a separate job. Please give me a bid for 1) BigCommerce work only, and 2) integrating the entire site, including BigCommerce. Also include the estimated time it will take (I need to get this live as quickly as possible). Thanks very much, I look forward to hearing from you.
