Here's how it works: Make an mp game and do the money glitch, go into single player and make sure all that money gets transferred. Now back into mp, depending on how big your going to do this you may want to do the glitch again. When you are back in mp name the farm with all the money "Bank" or "Dealer"
Next you should make 3-5 more farms, each farm will have its own role to play, one of the farms can be just for grain, one for animals one for logging and so on. With the new system you can trade crops between the farms and trade money, this could be done for contract work.
Use the "bank" to deal out money between the farms where you find its needed. You could also use the "bank" as dealership and buy a bunch of seed and equipment and "rent" it out to the other farms.
Now jump in and now you have 4 farms that can all interact with each other, play whichever one you feel like doing for that day, have fun!
