Hi, I'd gladly do it.
You weren't too specific though. Since this is a TV program I assume you have video footage to work with and also some graphics and concept ready? I could create a good trailer with that, I could also create motion graphics and animation based on an existing concept, so that's what my bid covers. Also, if you need voice-over for it, that would have to be provided by you.
If you don't have anything and all would need to be created by me, that's an entirely different story, then I guess my bid would be around $450 but very dependent on the specifics of the project.
You can check out my portfolio for some samples of my work and contact me for any further information.
Regards, Szilard.
