Hello and welcome to Purrs Karen!
Gosh less than 24 hours since we had our little cat meeting last night, and it looks like you will have your hands full soon!
I think it would be great if someone were nearer, but if they are like us, you know how it is.
I think she would travel better sooner rather than later, it is not as if we are in high summer, so she should be able to be made comfortable on her journey. Some cats are notoriously bad travellers, like my Turkish Van, who is not one you take into your vehicle lightly! Take a kitten pen or another large carrier with a small litter tray in it for her. Stop to offer her some water and maybe some light food.
Good luck Karen with your project, I have just ordered some wormers for the Group, so we will support you if you decide to take her on.
