Hi,.
Creating vDS is easy and there is lot of information "how to" in the internet.

Show Me How: Creating Distributed Switches in vSphere 5.5 - YouTube
Back To Basics: Managing a Distributed vSwitch (Part 1 of 9) | Mike Laverick...

but I think those links put you in the right track. Particularly Mick Blog is very detail and easy to follow.
Hope this can help.
