Drive Targeted, Converting Traffic to Sales Page

I have a sales page running here: [login to view URL] for a digital product aimed at fitness trainers and fitness marketers which provides them with a wealth of white-label (or, Private Label Rights - PLR) content relating to Kettlebell workouts, including exercise graphics and instructions, workout eBooks, banner templates etc. This product has done a reasonable number of unit sales from affiliate/JV sales and my own direct marketing activities. I am looking for motivated people who are have expertise in driving targeted, converting traffic to assist with generating further sales for this product. I am looking for an ROI of 2:1, i.e. for every dollar I spend with you to drive traffic I receive double that back in sales revenue. It is this benchmark against which your success and ongoing engagement with me will be measured. Please respond detailing: 1. what strategy/ies you would pursue 2. your experience and why you are suitable for the task 3. budget required and timeframe to produce results 4. preferably you will also include details of a very low-budget trial campaign that will demonstrate your skills in this area that we will do first before any ongoing/larger work is agreed Rules: 1. No blackhat or illegal activities will be tolerated - for instance spam 2. I have no other preference on how you drive your sales so long as it is legitimate converting traffic that results in legal sales - be it PPC, SEO (not recommended as this product lends itself more to direct response sales), Social etc. Respondents who fail to address the aforementioned criteria will be shortlisted out without further review or response. I reserve the right to place this task with any number (including none) of respondents. If you require further information please ask. Thanks Chris
