There was a place in the Miami, Florida area that did it professionally. Some photography stores send out their customers orders to them but you'd get a better price if you can locate them.
The film is likely to be in better condition than the video. The worst that will happen with the film other than stuttering if the sprocket holes are damaged is that the color may have degraded. Some places have the technology to manually advance the film and essentially scan each frame of the film. Of course, that will be much more expensive than if they can simply run it through automatically. It would be worth it to have the color balance adjusted when you have the film transferred to DVD.
The video will suffer because the glues that attached the magnetic layer to the tape is likely degraded and the magnetic layer may flake off. It's actually worse if the video has not been played because the magnetic layer can stick to the surface of the tape above.
Here is one service - I AM NOT RECOMMENDING THEM, I just find that they have some good information -
