Build me Email List

I need someone that can build me list in online marketing niche. I need 10,000 - 15,000 list subscribers. Details : 1. All email subscribers must be REAL people - no fake or bots 2. These subscribers must double opt-in (single opt-in not accepted) 3. Only subscribers that are interested in online marketing, make money online, blogging, webmasters I will verify all subscribers before making any payment. There will be 50% milestone created first, and full payment released once I verify the emails are legit. I know well how to check this, so don't waste your time if you can't provide real and genuine subscribers. Would prefer someone with previous experience in this. Budget is not more than $300.00 Bid with confidence.
