Suggest me Hosting for Wordpress demo

Hello, I want to knoe the best hosting for wordpress. My main concern is the “Bandwidth Limit”. My first wordpress theme approved last night BUT the bandwidth limit goes for 3GB out of 10 GB . Its less than a day! I’m in huge headache as this limit will surely cross tomorrow.

Is there any hosting available that has Unlimited Bandwidth ?

Or, Please suggest me how can i run the demo site with enough BANDWIDTH …
