Background images wanted for WP "panorama" app

Technology

We develop personal productivity apps for mobile devices. Our first product is a Windows Phone app that combines todo + time management + productivity, to help users spend their time wisely. Please visit our website, www.balancetask.com, for more product info.

We're looking for a background image to be used in our app. Requirements: - The theme of the app is "balance" (as in achieve balance in life) or "time" (as in time is money), so we're looking for background images that (ideally subtly) convey either of the themes - We'd like the background images to create a feel of our app being "vibrant", but in a controlled way (ie, all texts still fully readable, background image not dominant or distracting) since it is a productivity app - We're looking for dark and light versions of the images, to be used in Windows Phone's "panorama" view - The background images should be .png with the size of 1000 x 800 - We're looking for design that scales well to larger screen sizes (eg, tablets) and are interested to work with the winning designer in the future We attached four screenshots of our app - two are from the dark theme and two are light. Feel free to go to www.balancetask.com for additional screenshots. Ideally the current blue header (at the top of the screen) stays, but it's not a requirement.

Our target audience is working professionals who are interested to achieve higher level of productivity.

Every design category has flexible pricing for all budgets.
