thats tough. lets say we made $2000 a month from them, and we were cut off completely. We could say 20 years @ 2K a month would be reasonable as it was sure to grow. or they could say 2 years at 2K is too much because no more new players are being added.
I would want and expect at least 2X the last 12 months totals of actively working with them. So pretty much 2 years income.
