I have not been diagnosed but I am pretty sure I have ADD. Anyway, one of the coping side effects of ADD is hyperfocus. It pretty much allows me to do anything extremely repetitively pretty easily over a long period of time so in that regard I actually have an advantage. I planned on starting with say 1000 per month to test the waters and if responses were decent I would send as many as I needed to send for the desired result.
I actually had a program custom built to get all of this data. There is literally only one like it. I outsourced a lot of the coding work to a fellow I met on Elance that is in India and it worked our perfectly. I figured I wanted to create my own list which I have done in the past in unrelated businesses. Basically this program will allow you to put in Block and Lot numbers and search literally every property in any state. I loaded a list of 200K properties and it will tell me what every single one of them owes in Taxes and in Utilities. I am hoping to get a few thousand of them that will owe at least 10K in taxes. The reason for the post is that if I could then cross reference them automatically somehow to find which of those are absentee, Etc Etc... the list should be even better to market to.
