We're constantly putting up new content to help people get started. We have two different sets of video tutorials from Version 2 that still apply to Version 3 as the workflow and use of the interfaces and application are the same: http://support.presonus.com/forums/20934320-Studio-One-v2-Videos
We also have great collaborators who put out content for very little money. This is a complete series for $15 on how to get going with recording and studio one, this is perfect for you: http://www.homerecordingmadeeasy.com/made-easy-series.html
There are several books on Amazon, this one is for beginners from Alfred publishing.
We also have a great user forum with thousands of great helpers on there and tons of tips and tricks for you to look at to help you get started and get going when you get stuck. https://forums.presonus.com/viewforum.php?f=108&sid=4ac58f3257c112fe12e8dcf3ce166665
and there is this great site: http://www.studio-one.expert/
There are plenty of resources online and in print.
If you need personal training I can recommend Johnny Geib's http://www.homestudiotrainer.com who will (for a fee) train you on anything you want to know, even work on your mixes with (or for) you.
Hope this helps point you in the right direction.
