Wow, sorry to hear about this. 

The only thing I can suggest is (if you haven't already) to contact any remaining buyers that have not queried or disputed yet and let them know what is happening. Most will probably want an immediate refund, I know, but you could try negotiating a refund date that will give you some time to pay eBay and continue to trade, and at least they will be informed. 

Other than that, the only thing I can think of is whether it's possible or feasible to gain a short term loan, just to be able to get the most important things sorted and allow you to recover by continuing to trade.
