Are you sure you need a spinnaker sock, Joel?
I have been launching and dousing my symmetrical spinnaker solo without a sock. As long as the jib is up blocking the wind, it works fine. Dousing under the boom into the companionway by pulling the sheet works great - no problems as long as I release the guy, then the halyard.
I store and launch my smaller spinnaker from a Target laundry basket, secured with bungee cords (seen here on deck):
I store and launch my larger spinnaker from a traditional turtle, which requires a bit of pulling to extract while pre-feeding the guy.
