Another alternative and probably a good transition would be to move to trading full-time and keep your other job part-time, if possible. It's a lot of hours, but it sounds like you're already putting in the same amount of hours now.
Even if you keep your other job at just 10 - 20 hours a week, it will be of great benefit to your longevity as a trader. If your trading career hits a rough patch and you have to go back to your current industry, you're probably not going to be able to tell a potential employer that you took the past year off to daytrade -- much better to say you were a part-time consultant in your industry. Plus having a secondary means of income, even it's just enough to cover the basics, is obviously a great stress reducer. Then when you're rock solid, you can trade full-time with no other job.
