Commuting / Jumpseating on Cargo airlines

[LAHSOinMIA]

Just wondering if anyone has information on how to go about commuting on cargo carriers? (Fedex, express.net, UPS, etc.) I am just begining the commute from south FLA to Dayton, OH and have been told this might be my best, if not only, chance. Any help or contacts you could offer are greatly appreciated.

Best regards,
