Is this correct? Video Streaming

[D.ZINE_A]

Hi, I am having some problems implementing a Video Streaming Model for a website I am currently putting together.

The Way The Site WOrks:-
When a user enters the site and logs in, they will go to the streaming section, where there is a constant stream of videos being played. They will join at any point in the broadcast.

The Current Model:-
The current model consists of a high spec PC at our office location sending out a single stream to a rented video streaming media server, which will re-broadcast the stream to the x-amount of users viewing, through an embedded windows media player on our website. (The website will be on a separate server from the stream.)

The Stats:-
Stream bitrate : 300Kbps
Length of stream : a constant stream encoding 24 hours a day, where users join at any point during the broadcast.
Users viewing for : 3 hours on average
Total Users each month : 10,000 on average
Total Concurrent Users : 1,000 at peak times

bandwidth usage (GB) = (bit rate (GB/hr) * Viewing Length) * Total Viewers/month
(0.135 GB/hr * 3 hours) * 10,000 viewers/month
= 4050 GB per month data transfered

Transfer Limit (Mbps) = bit rate (Mbps) * Total Concurrent Viewers
= 0.3 Mpbs * 1,000 concurrent viewers
= 300 Mbps

The Problems/Issues:-
1. Cost
Implementing something like this with the model above is very costly. Does anyone know of another method for a lower cost, but one that does not negotiate on quality or concurrent users/total users.

2. Model
Is there a better model? Someone originally had suggested we use a co-location facility, whereby we send the stream from a rented server owned by a third party at a co-location centre. The only questions I do have about this are:-
Would I be able to run Windows Media Encoder 9 on it?

If so, if I was going to upload a new video, how could I edit it into the current playlist without disrupting the current transmission.

Could I choose a co-location, without rack space and just use the connection speed that they have access to to host my stream?

3. Any other suggestion/questions/issues
If you have anything that may help, or something you think I have overlooked please feel free to ask or let me know. I welcome all comments as I do not expect to have the best solution first few times round.

Thanks
