I dealt with a voluntary dissolution for a friend who had started a decking business a couple of years back and found himself in a similar situation, only the losses were much much bigger and he owed a substantial amount to the builders providers. He had a limited company, so it was different, however.
I was able to get some of the money he was owed in, by sending registered seven day letters and threatening solicitors action. They still owed the money and were trying to weasel out of paying, however, it did work and we got a fair bit in because the company was still there, so we could have started a legal action. Also, he came up with a repayment schedule for the builders providers and paid it off out of his wages. I know being a limited company, it would have been easier for him not to pay, but he was a very honourable person and would not see anyone out of pocket, due to what he called his "mistakes".
Good luck with it.
