copywriting needed for expensive, luxury weight loss retreat

We own a $7,000 USD per week residential weight loss retreat in California. We currently get 300 organic visitors to our website through SEO and another 500 visitors through PPC. We need to increase our ROI and have determinded that our web copy needs improving. We are looking for: 1. Expert copywriter with EXPERIENCE working with luxury, top 3% income market 2. Who can show through references or otherwise that their copywriting has directly increased their previous client's (or their own) conversion rates of their website. 3. Can work with me directly in a systematic manner to improve the copy throughout the project (In other words, this is not a one-time re-write of the website. We need to test different headlines, copy, and track the results). 4. Has a complete understanding of the English language (is fluent and/or a native speaker) and can write well. This project is for a home-page re-write. If your copy improves our bounce rate, retention rate, and lead generating, we will hire you to re-write the entire website. The site is [login to view URL] for you to preview. The best way to get my attention is to write a PM that will compell me to contact you regarding this project. If you send me a PM that says, "I am ready to work" or, "I can do this project" I will not respond to you at all. Thank you!!
