Newbie Question (Categories & Linking)

Hi There.. I am new to WordPress and the Enfold theme.. but am capable with bits of PHP and capable with CSS & HTML.

Basically I am creating a site with lots of blog and lots of pages (which is going ok!)
The problem i have is I want to link to the categories(blogs) and customise each, for example, this is what i have setup:
Public URL = /category/public-projects/
Builder URL = /category/builder-projects/
Architect URL = /category/architect-projects/
Case Studies URL = /category/case-studies/
Testimonials URL = /category/our-clients/
Portfolio (Masonry Blog) URL = /category/portfolio/
(This one is slightly different as it has 5 sub categories [Commercial, Educational, Industrial, Leisure and residential] I was going to save the sub categories for sorting / reorganising the masonry blog )

So I want all the links to have the category in the link removed and link to a individual custom category pages for each one…
am I thinking on the right lines here? or am i way of the mark?

I don’t have a category page with Enfold?
PLEASE HELP

Regards
