is there a way to maybe talk with some organisations? Here in Europe there are groups of people that could perhaps organise to have someone take them in a car.

I realise it may well be a very long way, but that is a lot of money.
Maybe you could hire a car and do it in a few days.
I don't know enough to know what options you might have.

But there are sure to be options if you think hard about it.

Good luck.
