ger,
ring a couple of landscape gardeners[big company] in your area and they may be able to direct you to someone who buys these palms.
They are sought after for very big developments. ie hotels.casinos
A bloke l know buys them around Perth and then sends sea container loads of them to Dubi, and many other oil rich countries.
Its big dollars and the demand is greater than the supply.
A very lucrative business indeed.
They also send sea containers of instant turf to the same countries.
Its worth a couple of phone calls for you. You may get a surprise $$ wise
