At my university most infrastructure in core labs is actually purchased by individual labs and then placed in a core with the understanding that the core will pay for the service contracts and run the machines in exchange for sharing. The major costs are personel and service contracts. Moreover, many cores are able to be self sufficient by charging users for services.

A similar system could be established here, or investigators could contract work out to 3rd party companies or even other university core labs which frequently allow unaffiliated investigators access, albeit at a higher price.
