I've seen an extremely wide range of timeframe depending on the business and market. Some as quick as a couple months to some being longer than a year. I don't think I can give an average that would be meaningful base on the number of companies I know of. That said, it helps to work on a cashflow project first to sustain living before diving into a startup like project that may take awhile to bring in enough profits to do the same. This is why some people recommend working on your startup on the side even though I know most would prefer diving into their startup overtime from day one. The problem is this isn't realistic for many people and underestimating things doesn't just go for estimates of when profit or funding will come in. It's in all areas.
