I don't think so. If you were willing to hire a team to implement some solution that existed in OSS form, why wouldn't you just pay for the OSS version, which would likely be cheaper (since you're spreading the price across many different companies). This is already the appeal of OSS - it's cheap, other people build and use it so it's well tested, etc. Those are significant benefits, and worth paying for over an in-house team.

And we already have pricing models for small/medium sized businesses vs large ones. OSS could easily have similar models.
