Shore Power Electric Power Conversion

Hello. I have a 2005 Bayliner 305 with 2 gas Mercruiser 5.0 liters mpi and generator
I will cruise pretty far away and will have to dock where power is 220V 18A. My problem is that the boat is equipped for 110V and 30A
I guess I need to get installed an international electrical converter. Any idea on how much does it cost ? And where I can find that and have it installed? Thanks
