Get a website (dude... not any website... ask me in pvt  if you want my opinion)And send postcards (don't bother with letters).

So a few days ago I went to my local Post Office and bought 500 prepaid postcards. 

You must also pay for advertising, wear and tear on your car driving for dollars, gas money, business cards, website, stamps for 500 letters/postcards per week, etc.  

Set up a website, started marketing- cold calling, FB, postcards.

It is not the scribbles and doodles you draw on the mailer.If that were the case you would be able to do data collection and it would have shown that 80% of pink letters do better.. and that every single person then sending pink letters would get better results.If that were the case there wouldn't be any yellow postcards right?

@Frank HinckWhat I'm using as my primary form of marketing is postcards. 

Older people remember voices and names and how you made them feel, not postcards. 

I'm still working on that software idea, but if it doesn't work out, I was thinking of getting back into wholesaling using the door knocking strategy.I don't want to go back to land wholesaling even though I was seeing some "success" because of the same reason I want to try door knocking (to set myself apart from everyone else sending letters and postcards).

You are looking at the bigger picture and you should take a more realistic and practical look here.Do you think BECAUSE you send 3 billion postcards out you will get a deal?

Based on the calls and postcards I keep getting for properties I've sold over a year ago, no one scrubs.
