Hi, I write a newsletter for pro AV companies that engage in this business.
1. What kind of setup is needed?
There is an industry out there making it easier but the separate components are:
- recording appliance
- recording software
- video camera (HD and with zoom) and camera tripod
- audio: microphone (for small events, can be built-in video camera)
- networks switch (could be built in the recording appliance)
- cables (very important)
- qualified person to run it (even more important)
- stable internet connection with good bandwidth (if you are live, careful before trusting a venue--and remember if it is an event, after you test the connection you will find it different with 200 guests hitting the wifi for their smartphones)
- might also need a video-ready network to ensure delivery (CDN) if you are playing in the big leagues
Suggest you look at this just to get idea: http://www.e-idsolutions.com/Collateral/Documents/English-US/IDS-Webcast-pkc-030310-01.pdf
But bear in mind, if you are working for enterprises you may run into issues of scaling larger (more cameras,more people for example.) Best way to get your answers is to contact the people that make the kit who need to explain it to you in order to sell it.
2. What to charge?
You charge what the market can bear. You check out what competition is charging in your area (o as close to your region as possible). You consider the size of company. Also recognizethedifference between live streaming and on-demand (commercailly as well astechnically).
3. Total costs involved?
Probably about $10,000 in kit if you are starting with size of compnay where only one camera involved. You could also spend a lot more and get more robust & better relaibility.
4. What kind of business model is ideal?
A profitable one. But most common is flat fee with overtime if meeting runs longer than expected (and monthly fee if you are providing the video on your network or CDN for on-demand for as long as they want it available).
5. And lastly do I need to hire a firm or someone who can bring in leads or business for me?
It sounds like you just want to own and finance such a business. There are plenty of Audio Video experts you can hire to run such a business: they can manage the technical and solicit customers. But if you are asking if the customers will beat a path to your door...no, never.
You might find customers by aligning with the PR companies that handle stock-market listed compnaies.
This is not as simple a business as it appears...but there are a lot of companies trying to make it simpler and you can find most of them-- and all your answers-- at an event like InfoComm (you have one in Bombay Sept 12-14).
Companies involved in webcasting often go into video conferencing, digital signage, rich media streaming as related businesses.
