Customize an existing e-commerce site.

I have an e-commerce site named EliteChhori ([login to view URL]). I want to customize the product page layout. Product page example : [login to view URL] 1. On the above page the description is shown below the product, I want it at the right side of the product image below price. 2. Realign the buttons Add to cart, pay now, wishlist and compare. 3. The header at the top containing the logo should be scrolled up on the product page automatically and only the navigation bar must be visible at the top without header. 4. The site has a category named Bottoms for which I want to have a color picker to be placed on the product page similar to this [login to view URL] . Notice the color picker on the right that changes product image when clicked. I have bought a plugin named Woocommerce Variation Swatches and Photos for the purpose but am not able to integrate it on the page. That's all for now. But I have still lots of development work to be done in the future and I am looking for an affordable and excellent developer to satisfy the purpose. Thanx in advance.
