The owners, property managers and agents who specialize in rental properties represented over 1,400 doors at the June KnoxREIA meeting and this meeting could be larger.

If you don't have a realtor representing you, you can negotiate the commission as part of the sales price, at least here in Oregon.  

I have a full time job as a scientific instrument sales representative, and I am normally on the road at least three days per week.  

Questions: I'm not being represented by anyone, should I look for an agent who can represent me in these dealings?

The agent is representing both of us.

First off, they are misusing the term "pocked listing" as to real estate terms, it's buzz, no big deal, but know a pocket listing is generally illegal by RE Commission regs, where an agent simply holds the listing contract and doesn't actively work it until they come across a potential buyer, they keep the listing in their pocket.I do not advise newbies to use a listing agent to buy, in a dual agency (which was misguided in that video) the listing agent represents the seller not the buyer.

No person shall engage either directly or indirectly in the business of a real estate broker, broker-salesperson or salesperson, temporarily or otherwise, and no person shall advertise or represent himself as being authorized to act as a real estate broker, broker-salesperson or salesperson, or to engage in any of the activities described in R.S.45:15-3, without being licensed so to do as hereinafter provided.

Unless you negotiate for it or represent yourself in an MLS transaction with agents. 

Hello, I am in the Milwaukee area and have a close connection who used to work as a claims representative, he says that if you're paying someone it will be about 6k-12k depending on the size of the roof as stated above.

I would agree that if your only reasoning is to gain MLS access than its probably not worth it but as a current wholesaler I would think you could expand your business with your license and not necessarily have to get into representing buyers and seller aside from your investors, which includes the resell side commissions for your investors who could use you for the sales on the tail end of their flips projects along with purchasing the deals you find for them on the front end.
