Fix eCommerce project

Hi We need help in fixing an e-commerce store. We did with another vendor to do but there was apparently some issue. Whats the cost for this fix? URL: [login to view URL] Updates of Categories: Acne Control Line Brightening Line Deep Hydration Line Ginseno Line Micro Technology Serum Respiration Line (sensitive skin) ADD in a NEW Category for 4 new products Stem Cell Line Special Line  *To combine existing Cleanser, Mask, Revitalise Line, Special Line into one  { Special Line } as customers feedback that we have too many categories and it can be confusing For e-commerce improvement :  1. Payment Gateway  Should be able to link to payment gateways by using API for direct credit card payment  2. Refund system  should be able to refund partially (specific product instead of cancelling the invoice) 3. “CONTINUE SHOPPING”  should go back to the previous page / last viewed category after clicking it in the shopping cart.  4. Photos  Take away the zoom in function (under the product description page) as it will obstruct the category selection on top (“SHOP”) button 5. To take away the + sign under Shop (on mobile optimization function) to minimise the shopping hassle 6. NO automated email acknowledgement for customer after purchase (only Paypal payment confirmation email was sent, and there is none for credit card details (saved) selection so the customer do not know if the payment has been approved) The person in charge needs to generate invoice and shipment emails manually. 7. To include Terms and Conditions on the main page 8. Search function (for example: if customer search for hydration, not all the products are related to hydration line appears) 9. Should prompt customer that they need to register before using coupon code 10. Under mouse over function which shows the preview of the cart, please allow customers to click on the cart and goes into the “view cart” page 11. The page doesn’t update on its own with the updated pricing. Adding or deducting of quantity and the pricing should be automatically shown for checkout 12 Might few more issues during work.
