I think You Should use VPS for this purpose.

Considering flv streaming demand the main question in your case is about bandwidth since using nginx to stream flv instead of apache or (OMG, don't tell me you do it) php script is very resource-cheap. A decent dedicated server will cost you under $100/month. Unmetered unshared 10Mbit costs about $80/month, unmetered unshared 100Mbit costs about $1k/month. There are offers of unmetered unshared 100Mbit for only $350 but I had no chance yet to check and verify that.

That's not always true. Sometimes a hosting company offers a promotional price to get new customers but uses their normal price for resignups. You get a cheap rate but also get a higher end service.

Other times you pay 15/month for a horrible company that locked you in for 12 months.

No matter where you go, make sure you have a way out. Refunds, cancellations, keeping the "free" domain. All of that. If you need to leave, make sure you can. Even if you find a ton of reviews.

Thousands of it will appear when search upon at online search engines. Since there are a lot of web hosting firms claiming to have the most affordable web host packages, it is quite difficult narrowing down choices.

I can put forward a suggestion to have a look at proaxxs.net and glowhost.com - these companies provide fast and uninterrupted hosting services and they are optimized for FFmpeg hosting services. You will save some money if you choose the one from them, as they offer attractive discounts.
