Step-by-step guide to direct mail marketing

[Vera Rosen]

Can anyone out there point me to a step-by-step guide to setting up a direct mail marketing effort? My partner and I have been investing part-time for a few years now and have close to 20 units, and a reasonable amount of liquidity to start purchasing more. We have not yet tried anything other than simple SFR buy and holds, but are now ready to try something new to start scaling up our business.

While I know there is TONS of info on Direct Mail Marketing (DMM), Wholesaling, and Subject To on Bigger Pockets and elsewhere online, it is almost too much... 

Has anyone found a single go-to source that provides a nice outline of how to get started:

1. Where to find/purchase lists
2. Where to find best mailer options - yellow letters, etc.
3. What phone services to use - google voice, etc.
4. Scripts for responses/screening calls
5. Scripts/process for initial homeowner interviews
6. Strategies to offer homeowner/seller options - cash buy vs. wholesale vs. subject to vs. MLS listing by agent (I'm an agent in Philly)

Ideally, I am looking for a simple guide to get us started, but also open to hearing about potential courses/gurus that charge reasonable rates to provide the whole system in a box.

Thanks in advance!
