Development Shopify Expert needed for some task

Hi, We have 3 little task to do. If you know shopify (expert level) this should be easy project. Do not applied if you have no coding experience ! =================== 1) We installed the volume discount apps from hulkcode. Our auto reload page does not work now to show the discount price properly. We required a little change : We need to adjust our shopping cart webpage to add 'Update' button under the product. We do not want to reload the page automatically each time that we increase the qty by 1. method 1: add 'update' button under each product. Demo: Screenshot: [login to view URL] method 2: add 'update' button under all the product list in shopping cart. Demo: [login to view URL] method 3: add 'update' button under the product you want to update. The button is show only if we change the qty. The page will reload. demo : [login to view URL] *** method 4: add 'update' button under the product you want to update. The button is show only if we change the qty. The page will NOT reload. Can update all the product for wich we change the qty.

We offer the free shipping for all order over 59$+ Method 1: On shopping cart, show 'Add $$$ more to get free shipping' with a design bar. Demo: [login to view URL] In action : [login to view URL] Method 2: On shopping cart, show 'Spend $$$ more to qualify for Free shipping' text. Demo: [login to view URL] In action: [login to view URL] * This information must be show on shopping cart page AND on the Cart summary of our website. Demo & Instructions : [login to view URL] ==================== 3) Change CSS style ( we do not want to have description, compatible, review tabs in bold text... ) see screenshot: [login to view URL] [login to view URL] [login to view URL] * To our product description, we have style ( css ). To avoid to put this style for each product, we need that you add them directly to the css liquid file. This will avoid to show the style code in the Quick View .... screenshot: [login to view URL] ==================== *** Our theme already work on any device. These task must be responsive and work on all device ! ** Will have more task to do. * Automatic Message will be deleted.
