An internet only firm with limited personal exposure and consulting will be cheaper. 

Get on the internet or start making phone calls and make an appointment and go see one. 

In today’s world of Zillow, Trulia, Redfin, etc, I could essentially list my own property for free, and with every one else scouring the internet looking for houses themselves, sell it easily myself.

I would need at least 4 clips per drywall sheet.In an internet search, the cheapest US suppliers that post prices appear to be charging almost $5 per clip, even in 1000+ quantities.

In this game you won't find deals on the internet.

@James Wise - fair point but as the market advances, their 8% - 10% plus aggressive placement fees, renewal fees, vacancy fees, the list goes on will have to come down or the likes of Hemlane.com and Buildium will begin to expand their service offering and make the "on the ground people" obsolete just like roofstock is doing to zillow and redfin or internet banking did to banks.

We don't need to worry about discussing information with 3 separate parties (Seller, Realtor & Property Manager)As I write this it's important for you to know my background as when you are on internet forums like this what you'll get is a lot of people jumping in and giving out opinions on the situation.

Has the Internet killed the coaching and courses model?

Was it using an internet listing service like  LoopNet, BP or via local brokers? 

Everything that you asked above.And sometimes it makes more sense to build than to buy, so we also have a 3-Day Developer's Academy that focuses on ground up and conversions too.So part of this may be a shameless plug (of course hopefully within the guidelines of BP) but also to preempt and let you know that there is a wealth of information available - a lot here can be procured on BP, and reaching out to folks like Mike Wagner, or on the internet like Inside Self Storage Investors, both the national & your state Self Storage Association, and folks like myself too - you tube videos, podcast, etc.So you'll not be in lack of information, but be sure that you're best able to simplify it, categorize it, & then action upon it.
