דרושים פרילנסרים לקאסטם תוסף בוורדפרס

Hi,
I need some help with customizing a plugin.
I am using the "WooCommerce Simple Auction" plugin.
because I am using this plugin, when a product is in auction mode, the inventory option disappears.
so, either there is an option to make the inventory option to reappear with all of its functions, or just to add an input field that a user can chose a quantity (even if it wont really be connected to the inventory) and that the field content will be shown to the admin in the email that he receive when a bid is placed.
hope i was clear enough.
thank's.
