Updated / Modifying Existing Wordpress / Woocommerce Site - 22-9-2017

Hi Freelancers, I have an existing websites that I would like to update. Please note *WORDPRESS* and *WOO-COMMERCE* expert only. 1) Add Plug-in "Woocommerce Bulk Buy Discount Plug-in Example.... [login to view URL] Layout Example... [login to view URL] Can be edited from quick edit 2) Chinese Product Names** can be edited from "quick edit" (Right now, the Chinese name can be inserted via the back end product edit page via customer text insert) 3) Add Chinese Names** on product cart page **Right now, the Chinese name can be inserted via the back end product edit page via customer text insert, and they are displayed in customers purchasing e-mails, product page, confirmation e-mails and many other areas already. 4) On the checkout page, besides the English, add Chinese translation for the words. 5) Add Photo Gallery, sometimes I have marketing events, and have photos. On a simple wordpress page, I want a plug-in that can display the photos in thumbnails first, and when people click on it, they can access the full pictures. Few Bugs and Maintenance Issues 1) Get rid of sub-domains that are not in used on the server 2) The current search bar set up is very slow, please speed it up 3) Home Page - Header logo is interfering with top menu 4) Improve loading speed of website, (i.e. improve scores and ratings of GT Matrix and Pingdom) Thanks for reading and your kind attention.
