@Aleksey Vinogradov - at least in my area, ready-mix companies usually only supply the product... you'll still need a contractor to place the material, unless you're doing it yourself.

That is why investors use cheap throw away materials that break down after so many years.

They have great materials.

They all promote it, not teach it, promote it as a way to get started and generate cash to do something else (mainly, do what they mainly teach).If wholesaling is a means to some other real estate end for you, you will make more money (and generate the cash you were hoping to generate to do the something else) partnering with someone who is an experienced, wholesaling specialist at it then trying to dabble in it on your own.  

I signed up and currently reading posts and Educational material on BP, and it's gold!

-GC is given revolving Home Depot credit card for material.

We will only pay subs and for material?
