I'm thinking something along the lines of a marketplace exclusively for entrepreneurs, where you'd create say offers or packages which employers can purchase, and on our end we'd go out and ultimately serve as your recruiter and find you work that fits in your schedule.
The issue is that founders don't have time to look for work and browse job descriptions, or interview --- so we'd need to make it clear that you have x amount of availability, you're being hired remotely, and at a rate you specify.
For employers, entrepreneurs typically have highly desirable skill sets --- even with limited availability and performing remote work.
Yeah, working on that feedback/validation as well. Typically larger companies lack innovation and are encouraged to hire entrepreneurs. Especially if you've proven yourself, and can show what you've done --- it eliminates a lot of uncertainty and validates your worth. But even if you haven't, if you can show what you're working on, and your skill set --- it's a big plus. I'd personally like to hire from this pool.
Again though, do need to validate from the other end and working on it.
