Bygg en hemsida

Hi, I need some help making some modifications to our e-commerce website URL structure. I want the URL structure to look like [login to view URL], but now when we post a product it looks like this [login to view URL], so the "keyword" is missing. Since I am on a tight deadline and don´t have time to research this further I decided to look for assistance. I need it fixed asap. Should be a quick fix. Project plan: I will send you wp login details and let you do your thing.. Thanks!
