Wordpress - Woocommerce Modifications

We have a Divi theme Wordpress site using Woocommerce, we have some small issues that need fixing. Please provide a cost and timeframe to fix the below. REPORT We are using the report plugin and require two small changes. - The report has one calculation issue, the column is actually doubling, however another column calculations can be taken. - Currently the report is showing all orders processed I want to only see orders that have been redeemed using the unique PDF plugin installed. PRODUCT PAGE • The tab plugin is not working properly. When you create a new product the tabs do not work and the only at the moment is the duplicating a product. • Variations – When a product is added with a variations the woocommerce sales countdown plugin is not displaying properly and the add to cart does not appear. Only interested in freelance developers not company with project managers.
