Send them a simple yellow letter.I have received a pretty good response each campaign.

how far away from your immediate area is it possible to do mailing campaigns?  

I'm not sure where you are as far as getting started but I would suggest getting started with a direct mail campaign asap.

I am getting ready to do a big postcard campaign and would love to have some integration for leads coming in through a live answering service.

I have tried social media, mailing lists, email campaigns, and I am working on driving traffic to my website. 

I started my campaign 2 days ago and I have received 12-15 calls with around 4 sellers that are motivated.

If I have about 400 dollars to invest in marketing in the Boston mass area (Dorchester, Roxbury, Jamaica plain, quincy) what do you local investors think work best, what companies work best for direction mail if you suggest this.Is 400 dollars enough for a direct mail campaign, is 300 dollars just to be sure I could commit for 6 months to a year ?

In your example, you created a great deal when others didn't see it by doing alot of research and undergoing a large conversion.If you want a game plan for direct mail, checklist of things to prepare, or scripts on talking to distress and motivated sellers from your campaign, I'd be happy to share.

I want to be 1000 percent sure I am not throwing money away on my upcoming direct mail campaign.

We've been doing a lot of online marketing successfully and really saw great results when we started to hire experts in the proper marketing channels to manage our campaigns for us.
