I would say it'd be cheaper, safer and easier to sail yer mates boat over here to be honest and forget flying a jet there until you are experienced at flying.... starting with your non-complex SEP aircraft.... otherwise you will wind up DEAD. A fool and his money are soon parted but in aviation a fool and his life are soon parted especially if money is no object.
Money won't buy you experience or skill - I know this can be a frustrating aspect of learning to fly for those financially afluent and we've all seen people like you roll up at the airfield waving a cheque book and expecting miracles but it's the hard bottom line which you would be extremely unwise to ignore. Think of your family's lives when you kill yourself if not your own.
