You've found the web's mother lode of irrigation information!

I was in your position 9 months ago...

Orbit has an online system designer that's free and specs their product but you could swap out for comparable parts from other manufacturers: https://design.orbitonline.com/
Rainbird.com also can design your system but you pay for their service I believe.
You could also pay a local irrigation company to design your system.
Hunter Industries also has a very good guide on designing your own system: Residential System Design Guide

I started with the Orbit design and tweaked it over a couple months based on mainly the Hunter Guide and what I read on the internet.
This forum is a great resource as well as the irrigation sub-reddit on Reddit.com.

Edit: Aaaand I was just about to add the link that corneliani added above!

 

Actually that link no longer hosts the actual tutorial.. here's the archived version: How to Design A Landscape Sprinkler Irrigation System like a Pro! - Irrigation Tutorials
