thank you everyone for your help !
That gave me a little bit of hope, he's worked as an '' electricians mate '' & apprentice since he was 16, so maybe we could argue the case? We can definitely wait until he's got two years- we're only up to £8,000 in savings at the moment anyway! & Like you said he'll nearly be 25 so I'm sure we could hold out another month or two till we put in the application.
We'd definitely rather go PR but judging by responses we might be better off going for an employer sponsored temp visa then applying once we're out there, originally we were worried about buying property but realistically I don't think we will for at least 3/4 years anyway..
I think we're both a bit skeptical about using an agent mainly as they seem so expensive and it's already costing a fair amount!
