Hi!
Good luck with this. I have my own business too, but it takes awhile to really have it go well for you. There are grants from the government you can get although I personally never used them. Why don't you ask someone at a university close to you that offers non-credit classes in starting a business to see if there is someone there who can help you out(without taking a class). They do have classes on this stuff, although the idea is not to take one with your limited resources. Tell them your situation, they may be more ready to help. In the meantime keep your day job until you can switch over to your business as support. Take a non-credit class (if you can afford it. Maybe borrow money for it.) on how to market your product too. That helps! Good luck!
