Configure WooCommerce & Gravity Forms Product Add On

I have a website which I am building for a customer who is an online print store. We are running WordPress, WooCommerce, Gravity Forms and Gravity Forms Product Addons. The most complex product is A4 BROCHURE. I can provide a pricing table example which we will work to. This includes table rate and extra additional options which are to be added to the ORDER rather than the table rate. At present GRAVITY FORMS PRODUCT ADDON is not working. This needs resolving first. This is an urgent job which needs completing within 48 Hours. Please only message me if you can start right away. I also need communication via Whatsapp or Skype.
