[General] We will meet at the end of this month....

[Silverobama]

I knew the university English teacher Kevin last year and we became good friends. One day he asked me to join his dinner with his friends. His friends are also English teachers. Then I met and knew Frank. During the dinner, we three (Frank, Kevin and I) decided to meet at the end of this month to have a chat to see if we can find some opportunities to do business together. (For example, to run a coffe shop, to teach students and so on.) I wrote a sentence to conclude this:

We will meet at the end of this month to see if we could come up with an opportunity to do business together.

Is my italic sentence natural?

See above. Your italic sentence (with my correction) is grammatically correct but it's rather formal. In everyday language, I'd say something like "At the end of the month, we're going to meet up and see if we can come up with some ways of working together".
