    We have a Magento2 website that uses a Live Auction extension that works perfectly, but we want the design (UI and UX) updated to look better. ALL current functionality works PERFECT as-is, but the design looks like it's from the 1990's :( The primary job is to re-design the GUI. If you ALSO have the ability to customize the base functions of this M2 plugin, you will be preferred. We will require some customization and maintenance in the future. Make sure to read the attachment(s) and include the required CODE in your BID or it will be considered spam, ignored and removed.
