It's likely you won't be able to find a specific stream to restream.

To get directly from the source, you'll likely need to cough up a couple hundred or thousands of dollars for the month. And usually you'll have to take a group of stations at the same time.

Likely your cheapest way of accomplishing what you want to do is get a capture card for your pc as they can be found for less than 200, then hook up a legit cable box to that and restream that way.

The bonus is that you'll always have the capture card if there's a special even you want to share with friends. And if everyone chips in a few bucks it will pay for itself fast.

Paying another provider for one or two streams at this point is certainly not worth it.

Be careful of people offering channels for bitcoin, we've seem an increase in scams recently and there are some posts about that in /r/iptvreviews as well as /r/iptvgta

It's not really feasible because

1 these stream providers are cloaked in secrecy

2 you'd probably need a specific VPN setup to connect to their streams

3 they're just streams, the IPTV provider must handle the EPG data and package them together in an m3u in some meaningful way.

For more stability you can try sling TV, PSVue, or DirecTV now. Sky has a service called Now TV, but it's pretty trash for anything live even compared to even IPTV.

Most stream sellers don't sell direct to consumers.

Edit:

oh and maybe the exception to that might be Epicstream. I believe they own some of their own streams for USA, CAN. These are the streams with "E". (I can't confirm this, but I have seen this posted here in the past).

/r/epicstream for more info.
