I found a concept I liked at http://beautiful-email-newslette…. Did a mockup in Photoshop to match my brand and exact tastes and then found a great coder by searching 4-star+ “Responsive HTML Newsletter” designers on http://Elance.com. Mine was done for $100 and was pixel and code perfect. The best coders will share that your email will look perfect on all screen sizes by using http://litmus.com or http://www.emailonacid.com/. Even though I did my mockup in Photoshop, you can scratch yours out on paper and create a PDF to hand off to the coder.
