Big Cartel Store Customization

Hello, The job requires customizing a Big Cartel store to mimmick a design which I will provide. I would like someone who is familiar with Big Cartel and their parameters, or is familiar with customizing shopping carts in general. The store will be linked to the site - not integrated to the site itself. You won't have to worry about entering inventory as i'll take care of that myself. In total you'll need to complete the products page as well as the product detail page where visitors will find out more information about the product, view photos, and purchase. This also requires placing of JQuery Image Slider on Item selected page – so customers can see different colours and images of the product (Again I have a link to the free slider we wish to use) That's it! Please let me know if you have any questions. Ideally I'd like to have this completed ASAP so please only submit a proposal if you're familiar with customizing shopping carts and have the work to back it up. The site should also be compatible with mobile devices so please let me know how that will factor into the price. We will review only a candidates who already did same projects. So you should include same projects that you done. You should provide max job duration. Please put the word "umbrella" in your response to indicate you read and understand the requirements.
