If you want to look at it in a realistic way the NO there is no one who is going to be able to provide that NO ONE I mean I am sure you can hop on down to the hosting requests forum and I bet someone will off you 300gb for 19.99 a month if you ask for it, but the point is if you even use remotely that much bandwidth you are going to be back here looking for another host within a week. If you really need that much bandwidth I suggest just going for your own dedicated they can be found for <130.00 a month and it will save you alot of time and trouble..
