Frank, Thanks for the advice I appreciate your help and this forum.There are numerous places that sell lists, however, I have discovered that all lists are not created equal. Some companies make a concentrated effort to up date their lists on a regular basis, some apparently don't in my experience. I have purchased lists where the person died 5 years ago, hasn't lived there for a number of years, etc.
Although you will run into that occasionally with all companies, Lead Concepts' lists seem to be the ones that I consistently get the best information from. I pay around $100 per thousand for the parameters I request.
You may find other companies that you think do a better job.
