1. Buy a 1G/1G or 10G/10G whatever link to a building you own.
2. Resell that link in parts to customers.
Or you can get yourself into a POP (point of presence) somewhere that multiple providers are also in, and get transit that way. Depends on where you are and what you can get access to.
Something like Seattle IX is a good example of where lots of peering sessions could be established (although I haven’t looked at Jared’s ASN in any detail to see where it’s present).

Any traffic you’re able to offload via peering you wouldn’t be paying an IP transit to haul, so it’s worth seeing if networks like Netflix are on the Route Servers (https://www.ams-ix.net/ams/documentation/ams-ix-route-server...) at any IX nearby your network, seeing if you can negotiate a session over the IX even if they don’t participate in the RS, or seeing if you can do PNI (sling a cable between your networks in a facility you’re both located in).

If I have 1Gbps line for example and 10 users each are using equal amount 100% of time, it shouldn't matter they send the data to Alaska or Russia or Australia ? Or does it?
Do you buy the pipe and the data itself also?
