I don't think 6 years "trying to do a startup" is the same as a complete lack of work experience, unless you spent the entire 6 years trying to raise money and making powerpoint slides. If you did any real programming work during that time, it still counts. I've seen plenty of resumes with "sole proprietor" type jobs. Maybe you don't get a job with a large company, but someone who is versatile and used to doing whatever it takes is perfect for someone else's startup.

I don't think it is wise pitching yourselves to companies who are hiring 100K+ engineers saying you are willing to work for minimum wage. It shows a lack of confidence that you are selling yourself so far under market. Pricing is often a signal for quality. More importantly, the cost of a bad engineering hire is far greater than the salary you're being paid -- a bad engineering hire takes time to get rid of, and often produces negative work output. People end up cleaning up a mess, opportunities are lost while a bad engineer flails at what should be simple code, etc. A bad engineer could work for free and still be a worse value for a company than an engineer making market rate. This is the signal you're sending when working for minimum wage.
