Twitter profile background graphic design

Information on the business: My personal Twitter profile
Industry: Business
Design details: I'd like someone to create 2 or more versions of graphics for my Twitter profile @itscatho as the background photo behind my profile photo. I imagine a map of Asia and Latam highlighted with some sort of visualization or representation of linkages.

Try not to put anything really cool or interesting right where the profile photo would cover it. Please check the size requirements/suggestions for Twitter background photos.
Target audience: Twitter followers
Ideas for the visual style: Professional, sleek
Preferred colors: Positive feelings
Urls to draw inspiration from: http://www.sinolatincapital.com/index.asp,
Where the design will be used: Web, on my personal Twitter profile
Extra notes: Prefer a map where it's scaled (round instead of flat). Country borders and city dots not necessary.
