Hi nsul and welcome to the forum
An IVA is an option, but it seems to me that you guys are not realising you maximum potential by continuing to batter away in self-employed businesses which are not producing sufficient profits. Is it not a better idea to both find jobs that pay you a regular wage, get your debts paid off and start enjoying life again?
Also with an IVA, you will need to demonstrate regular earnings, even if you are self-employed.
