I have a chronically ill partner, and medication is expensive. I'd like to be able to do this full time, and it would therefore have to cover those expenses.

Sorry to hear about your partner.

If you are reliant on that expense and at the same time trying to start a business -- you might consider finding traditional employment while trying to get this business going.

Starting a business can be rough at the beginning. And you may not want that stress in your life.

Thanks for the advice, and the sympathy. I am indeed looking for traditional employment and doing a contracting project while I search. With Usability Feedback, I could pretty quickly put something together and figure out how viable the idea was, so there's not a huge amount of risk and stress involved.
