My 45 laff toon, Daisy, had that same task and I finished it yesterday.
It's not that hard, just bring some of your friends or find a group to go with. Let them know that you need to complete a factory (through the SpeakChat), and I'm sure they would be willing to help you. I went with some higher laff toons yesterday, one of them a little above 60 laff and another around 100 laff. We successfully completed the factory, and I didn't even have to use all my gags.
