My day job is building material sales (lumber, doors, windows, drywall, block, shingles, etc).

What are some good programs for CRM, lead generation, marketing and advertising?

The property was advertised with a new heating system. 

My property manager brought with them multiple contractors who they'd worked with over the years, receive and forwarded quotes and then assist in the decision making of materials, future development and the area to purchase. 

I've listened to, read, and watched hundreds if not thousands of hours of material over the past decade, but have not or do not remember advice regarding accelerating your purchasing power.

The MLS is just an "advertising method" like a newspaper ad or TV commercial.

They were both advertised locally on the mls pending an unsuccessful auction sale.

This included all material and labor and installing new flooring once the beams were replaced. in my case all the beams were replaced.  

Who will purchase supplies and materials, etc? 

As an employee, we get a fairly substantial discount on materials.
