UI/Landing Page/Conversions Expert needed - Design/Wireframe/Consultancy - repost

I'm looking for an expert interface designer, someone who has had a huge amount of experience in designing landing pages/sales content and putting steps into play to increase conversions. I need you to assist in designing several page layouts and taking current landing pages and increasing their productivity. I am a designer and have a lot of experience, but need a second professional opinion. Please show me 2-3 examples of your work and give me several good reasons as to why you are the best person for the job. Thanks, look forward to your bid!
