Fatsia Japonica

We have about 60 outside homegrown fatsia plants all over a year old now. As we are moving house soon we have to find new homes for most of them. Up to now we have sold only four (our idea was to sell them to increase our income!) but they are slow to sell. We have given some to friends and family but not sure what to do with them when we move!? They are currently in pots and healthy. Any ideas?
