An IVA might be a solution available to you, but being self-employed you would need to take specialist advice tailored to your circumstances. There is a statutory requirement for all self-employed people to have a face to face meeting with their nominated insolvency practitioner, which will mean that you will have the opportunity to explore all options and weigh up the advantages and disadvantages of each one.
Bankruptcy proceedings would seem to be inappropriate given that you are homeowners and both self-employed, and I would not recommend a debt management programme given your ages and the quantum of your unsecured creditors.
