Have you tried a Google search ? You should get many (free / paid) results.
You probably need more than a template. I suggest you take an online course from Lynda.com. They have one on producing a magazine with InDesign. And you can get a 10 day free trial!
(I have no connection with the company.)
This is a very useful reference book: http://www.amazon.com/InDesign-CC-Visual-QuickStart-release/dp/0133953564/ref=sr_1_2?ie=UT F8&qid=1449387669&sr=8-2&keywords=Indesign+cc
And of course you can ask specific questions on this friendly forum.
I'm with you on that Derek!
Magazine work is tricky and you really have to be aware of how it all works. If you're getting it printed you want to avoid additional costs for a prepress team to make your magazine print ready.
Of course - ask questions here. But I don't use templates, I create my own, and that's how you make a magazine.
