Welcome back, Ben. You're welcome to send me a sitemail as well. I'd also be happy to answer any questions you might have.
I will say it doesn't really matter when you start scouting - whether it's immediate or not doesn't make a difference, as long as you have a lot of your scouting done to have recruiting targets when phase one of recruiting starts.
There's a thread on 3.0 here

It's a huge and very intense guide. I like this "quick scouting" part of the guide...
(from the linked thread)
FAST WAY TO SCOUT ALL PROSPECTS TO LEVEL 4 IF YOU WANT TO FOCUS ON A RELATIVELY SMALL AREA - ABOUT 5 MINUTES
1. FSS the states within your immediate area
2. Hold a private camp, inviting the maximum number possible
3. Sending out the assistant scout to recruit people up to the next level. You can do 25 at a time. You may have send the assistant 2-3 times.
Using this method, you actually have more information than in the current game because you know the high highs and low lows.
Alternately, If you were not in a hurry, you could go to a public camp in your region before step 3 and wait for the camp to run. At that point, there would be many players already at level 4, so you could save some money on the assistant coach, and you would have discovered some new players that were outside of the area that you FSSd.
