Honestly, and I hate to say it, it's nearly impossible that your team would actually get into the NACS, and even less likely to get into the LCS. Let's just look at the Open Qualifier winners from the past few years. Delta Fox, owned by Echo Fox, has won twice. For the summer one, CLG Academy, obviously owned by CLG, won. Most of the other teams that have come into NACS were made up of Challenger players, former LCS players, and imports from other regions. Hell, GCU has multiple Korean players and all professional veterans and they still missed LCS last split. The only team in the past year to get from CS to LCS in NA recently was C9 Challenger, which was literally an LCS team for years. If you go back from that, you get Apex, a team with three Koreans and mostly pros. Then you get Team Coast, a team that won CS every year they were there, and you can keep going. A small startup of friends is just not going to make it nowadays, there are way too many big teams and big investors that are going to get there first.
Now, at the same time, you could use this to get into NACS. If your team is really good, a team might pick you up as their Challenger team, and you would get to play in the new Academy League under a current team's banner. Alternatively, if individual members of the team are really good, they might get picked up onto the Challenger teams. Really good, but undiscovered, players are definitely helped by this, since orgs can get them out of Challenger and test them out in actual competitive play.
