Show range of services

I want to be able to show my services in two different categories, so I need to separate the them but don’t know how. Here’s how I’d like it to look:

Personal Services:
(Show services 1-8)

Technology Services:
(Show services 9-12)

But the only thing I see in the documentation, calls up only the first services.
