I recently talked to a guy just south of Annapolis who has a heat/vac system for core drying. I contacted TPI about this process and they highly reccomend it.
The guy in Annapolis is going to charge $325/day and thinks it will take 2-3 days to dry out the core with this system. I had heard about this system previously from a guy near Philadelphia, but didn't pursue it because his cost was prohibitive. So you definitely need to shop for the best price.
