Gena from WinAHouseCompetitions.com submitted the following question to AskMissyWard.com:
“I like the way your twitter page has your photo and info down the left hand side of the page! Where did you get your twitter template, it's cool!”
I actually designed the background myself on Twitter.com/MissyWard, but there are a number of companies out there that have done backgrounds for friends of mine:
Auggie4000.com – Auggie charges $20.00 per background. You can see samples of his work and purchase online here. After you've completed your purchase, you'll receive a form via email to complete, letting Auggie know what you want. (I've used Auggie's services for a number of banner creatives and he does a great and fast job).
TwitterWallpaper.com – My friend Julie recommends them. Looks like they charge $75.00 for a custom Twitter background.
TwitterImage.com is another company that provides custom Twitter backgrounds. I haven't used them, but they've done a number of high-profile Twitter users. They charge $100 per background.
