I think of broker / dealer lists and operations where hundreds of folks are cold calling and getting warm leads then forwarding those to folks willing to buy the lists.  

It looks like you are acting as a dealer in this case.  

Go under the dealer section of appliances and then you'll be able to find local small stores.

Him and his girlfriend showed up in new cars with dealer plates (Escalade and Corvette).

Will the LLC be considered as a dealer or investor considering that it will be kept for over a year?

A similar selection bias is probably at work in real estate, when, for instance, people sell houses after they have appreciated a lot in value.Here's an illustration of the way this works in the art market:Imagine two paintings were purchased at an art dealer in 1972, each for $10,000.

I have come across several online broker-dealer platforms, and wondered if anyone has any experience using them? 

I'd imagine since it has been over a year you would pay capital gains (since you wouldn't have done enough flipping to be considered a dealer.)

They just explain it to their broker dealers/bosses and it generally is not a problem because it is not seen as competition. 

As a side note I buy sub prime auto notes (I really like that business, they don’t pay, repo the car) but I was talking to the dealer who’s been doing this for 30 years and he was saying it’s tougher now as the internet has increased competition etc.But again as you said this is not so easy from what I see.
