Colin Minto sent this over to me recently and I said I'd happily give it a mention. One of the job boards that Brainhunter run is from the Institute of Sales and Marketing Management. They also run SellingSuccess.tv which is a portal of sales training videos.
They are split up into categories such as networking, motivation and presentation skills. Videos are provided by a large number of different "trainers". You can view Colin's video here.
You do need to register to see the full videos but there is some good stuff on there.
