That reads pretty much as "good luck with that!" to me, I'm sorry. People would pay you exactly because they would never have a facility of their choice and in case it goes sour they would probably have to face a ridiculous price tag from some other new company not truly interested in keeping their sperm but that just happened to be part of your risk hedging or simply of a insurance deal.
