Thanks everybody, some really good ideas there. The plan is that i definitely won't work for the first 6 months, and in that time i'll focus on getting us settled. After that i feel like i now have options, and i suppose the best thing to do would be to see how things pan out when we get out there. I'm just a bit impatient i guess, and i'm generally worried about how we'll get by out there - it really feels like a leap into the unknown.
It seems like the options are to work for myself, which is actually starting to sound appealing if there is a genuine shortage of tradesmen out there, or using before/after school clubs to allow me to be employed, which would also work for us.
Thanks again for the replies, i've had my worries quashed... until the next wobble!!!
