Shared video files via internet

Hello, I am seeking advice from those wiser than I re: internet and such for a business I am opening. It is a hockey training centre located in Ontario, Canada.

I have rogers extreme at home, with bell for my local phone, a palm treo via bell mobility, and rogers cable. hoping to secure a deal on those when combined with my business account.

We do 1on1 session training and I want to videotape the sessions and make them available on a server for the students to download from home. However I am not sure how to accomplish this, and which ISP would provide the best package to make this happen. I am looking to use a high-end mini-dv camera to record 30 minute sessions directly to a laptop and then move that file to a server (at least that is what I think I need to do).

For phone service I am looking at the Vonage package as it appears better versus bell and rogers.

For cable I am leaning towards rogers because they have the super sports pack - however with the hd package (using 32" hd lcd tv's from tigerdirect) the price gets costly.

for my internet service - not sure who to go with, sympatico or rogers for business - guess it will depend on who can do what I need with the video server better.

Also - if I buy a router such as a DLink Wireless N with a USB port can I add a hub to that port and split to connect two printers and two hard drives for access by everyone on the network?

thanks in advance to all who can offer advice - obviously for the services I am hoping to hear from existing business subscribers to see what their thoughts are, and I hope to get some wise thoughts on the best way to setup the video server I am looking to offer my clients.
