The shipping won't be much, we'll just be shipping essentials so don't envisage a large outlay. Reading around it seems like £5k would be approximately the cost for the dogs, with flights around £1.5-1.8k, I can see £10k being about right. But I could be wrong, haven't looked into it all. We have to sell our house, which should net us around £15k, and 2 cars, around £2k, pay off some stuff, maybe £5k, so we should be in good enough shape.
That's another thing though, selling the house, that could prove to be long and arduous and we won't be able to pay for anything until that is done. So that could be another delay! Everything really adds up, in time and money, whenever you start to think about it!
Dunno about relocation allowance at the minute, I'm pretty sure they'd help us out to some degree, I suppose I'll have to wait and see.
