First of all thanks for choosing our theme, and I'm sorry to hear that you couldn't find widgets available in the theme that you are looking for. But we have a bunch of custom elements in the Cornerstone and Pro page builder which helps to build any kind of design pages. The elements are similar to widgets, you can drag and drop to build your layout.
You can check the Knowledgebase for more clarification and how to use them.
Regarding the portfolio page, you can use any of the grid extension coming with the theme to make custom design portfolio page. Please check this two extension it might help you to get started.
Is there a specific look that you're trying to achieve? I'm sure that we help get you set up if you give us a bit more information.
Also I noticed that you had a Pro license, but did you know that our X theme includes a range of expanded demos that would give you fully stylised pages, from which you could simply swap out the content as you need to? We'd be happy to get you on to that if you would prefer to take that path...
Either way, if you have any specific questions regarding our themes, we would be very happy to assist you.
