Q1: You should find developer to do the landing page and many different versions of it for testing which gives most traffic and email addresses. After a while just keep those that actually work with your marketing campaign. Q2: Simple google hack gives you easily email addresses from forums and other websites where this niche group shares their email address publicly. Query something like this "@gmail.com site:mmorpg.com" the email address domain works so that it will search for email addresses from that email provider and the site keyword specifies the website where you want to find the email addresses. Anyway with a landing page you should use google adwords for advertising campaign instead of trying to spam users to get their email address which you already have.
