I saw a post mentioning your site on one forum asking something about buying email lists.
I would personally recommend that you consider using a Yellow Pages scraper such as Ivy's B2B Leads Miner Yellow Pages Scraper.
I cannot find the link but you can google it.
I am using it for generating my own B2B leads and it is so much cheaper than buying your own lists so don't waste your money on pre-made lists.
Anyway mate, I hope this helps.
Take care and best of luck with your business!
