Clients are gone, lots of debt, what would you do?
webwright: With no cash, you should do what will get you cash ASAP.  That decidedly does not mean launching a product-- products take much longer to get off the ground and have some front-loaded cost.  That leaves services-- i.e. consulting or lead-gen/marketing stuff like you were doing before.  Hard to tell, but it looks like a low margin business (or you managed it poorly-- no offense!).  If you were pulling in 70k per month at one point and ended up in debt...  Doing more of that doesn't seem like a good idea.  The best way to get out of debt is to get a job (don't let a lack of CS degree stop you) or (if you've got a good network and/or sales chops) do high-end consulting ($100+/hr).
