So those few tips can get you on right track to make your own trailer.

I was a beginner at first.. and I still have way more room for improvement. On the side is my first trailer. Have a look and look how much I've learnt? and how my trailers have evolved. No ones perfect. And you gotta start somewhere. I actually have done a bunch of things that now I know not to do. If you want me to have a look at your trailer leave the link in the comments and I'll give a response? Yeh. Anyways I hoped this helped:) 

If you make a trailer using this guide leave the link I'd love to see it:)
