The right-offs don't really have a great deal of impact Blue. I'd just look at the op cash burn of $150kpcm. Net quick assets at the end of the year of $257k. (cash $1,590k / receive $671k / cred $2,004k). Maybe up to $1m after post-balance sheet events. Gives you 7 months all things being equal. It will indeed be close!
Come on EMS. You can do it!
