Ever Built a site to sell motivated seller mailing lists?

[Kenneth E.]

Hi all.

I am pretty good at getting mailing lists that few others are able to get (In one particular county, anyway).

However, I am considering building a website where I can sell the unique mailing lists that I am acquiring, merging, purging, cleaning, etc.   

Do any of you have experience in building a site that will allow you to sell mailing lists through?

If so, could you reach out to me? I need some advice.

Thanks!
