Okay. Let's take stock. From what I understand...

Your Resources:

* A partially complete web app, for patients with chronic conditions; helps them manage their problems & has some social network features.

* Feedback from your alpha testing.

* 45% equity in the company (with the ability to recover the extra 29%), which owns all of the IP.

* A limited amount of time before you must seek means to support yourself.

Your Goals:

* Develop your web app to a beta-worthy release.

* Get funds to develop to a point where you can charge, or maintain it long enough to exit.

Your Obstacles:

* Your user-interface isn't presentable enough to for your app to go public.

* Without a developer, you have no means to improve the front-end of your app, or implement new features.

* You have no funding left, very little personal money, and debt.

What I think your plan should be:

1) Ask yourself if you truly believe that your app can be satisfactorily profitable. Ask yourself if you're willing to work hard over the next 2 years (at least) to make it happen.

2) Reduce your expenses as much as possible. You said your monthly outgoing is $2,000. If I can live on $800/month in Boston, you can reduce your expenses to at least $1k to $1.5k. This pushes back your horizon for total cash failure.

3) Increase your income, even if it's just a short-term influx of cash. Whether it's through another loan, selling non-essential assets, or fully-booking half a month with temporary gigs.

4) Learn to code, and instead of continuing development, modify your user-interface to a level where you can release to users. Forget about advanced features. Basic functionality in a working interface, with the promise of advanced functionality, can get enough signups to take you to the next step.

5) Offset costs, and/or get to profitability. You haven't shared your business model; if it's offering the app as a white-label service to institutions, focus on getting your first customers once you have the basic functionality in a working interface. A modest amount of users, however dispersed, should be enough to at least demonstrate interest, and get them to license it from you on a trial basis.

If you're intending to monetize it through users directly, charging isn't feasible until you're offering advanced functionality, and advertising isn't feasible until you have a ton of users. But affiliate sales can generate income with even a modest number of users, and it's likely that the nature of their conditions makes them likely consumers for specialized products, possibly that are highly profitable.

6) Focus development on rapid iteration. Prioritize your feature list by simplicity and usefulness, and either split your attention between adding small, useful features one at a time while working on the larger improvements, or outsource development of the small stuff(one at a time, so you build relationships and can measure quality) and focus solely on the larger improvements.

7) After the three to six months the above should take you, take stock again and consider if you want to get another co-founder (if there are some really large improvements that need to be made that are out of your coding league completely), and/or seek more funding.

8) Let us know how it goes!
