Hi debtsucks! And welcome to the forum
To propose an IVA, you have to have a realistic prospect of returning a dividend of at least 25p in the £ to your creditors, and potentially more if you have debts with HSBC or Northern Rock. The return to creditors is obviously only possible once the costs of running the IVA have been taken account of, so I feel minimum payments in the region of £350 per month ought to be more realistic - but of course if you can afford to pay more you will be required to.
As you have no income, I do not feel that an IVA is an option for you at present, and do bear in mind that you cannot leave Student Loan debts behind under bankruptcy proceedings.
If you have a lower disposable income, and wish to avoid bankruptcy, you could always offer a Debt Management Programme to your creditors, but this will continue until the debts are repaid in full and ongoing interest is likely to be charged.
I am not quite sure what you mean about a joint IVA. In reality there is no such thing, but what has developed into a common practice is for spouses to propose voluntary arrangements where there is a combined contribuition distributed amongst all creditors equally. This would only be possible in your case if you were in a long-term relationship and if your partner has debts of their own.
My gut feeling is that you should offer token ongoing repayments to your creditors until you find a permanent job, and then reassess the sitation as at the moment things are very uncertain for you.
