Add 1000 subscribers to my weight loss email list

Hello, I'm looking to increase subscribers to my weight loss email list. I have set up a page on my site that basically tells visitors to optin to my mailing list, which is 100% FREE. Once someone enters their first name and email, they then need to click a link in their email to confirm their subscription - this is in order to avoid spam complains or automated parsing of email addresses. I'm interested in USA subscribers mainly. Sure, a subscriber here and there may be from another country - but at least 80% of the subscribers need to be from USA. Also, the visitors need to be genuinely interested in losing weight. I have big plans for this list but, for now, I would like to do a test project of 1000 subscribers. If you do well with it, I can give you as much extra work as you want. I'm really on a deadline here so this 1000-subscriber project should have been completed in 25 days max. Please only bid if you are confident you can complete the project on time. I will escrow payment as soon as I start seeing some results - say the first 200 subscribers. Please PM me and tell me what experience you have in projects like this as well as how you intent to promote the page. Looking forward to your bid!
