Searching for a structured course

I moved to this small town and there isn’t a BJJ gym anywhere nearby. I am a blue belt with 2 stripes from Gracie Barra, so obviously not knowledgeable enough to start anything. The thing is, I really want to roll. I found 3 colleagues from work that would be willing to learn jiu jitsu. Is there any good online course that has a good structure?

Like, white belts should learn this, in this given sequence. Once they know that, then they can start exploring the positions that they like more. Then same thing for blue belts, fundamentals in a given sequence.

Most courses that I found are not structured. I am inclined to take the Gracie University Combative course and start with that with my friends. All suggestions are welcome!

Thank you!! Oss
