Targeted Marketing from Scratch

[Ed O.]

Good morning!

I have a solid understanding of marketing to sellers after having listened to a lot of the podcasts, etc. Where I'm hung up is how to build it from scratch. 

Here's my scenario:

I've identified a limited, specific geographic area I'd like to purchase within. I can access records and data from the areas GIS and county database. I plan on farming this task out to a VA.

What I need, is a way to collect, sort and process the raw data, in the most efficient way. What software is preferable for this? I figure I'll mail marketing pieces 5-20 times to each parcel - I'm looking for a way to automate this part as much as possible - to a point where I can enter the property data and details - and then track and send marketing as planned. 

What's the best path on this? Thanks!
