Personally, I wouldn't have the heart to trash the fry, but you might need to. Either you kill them painlessly right now, let them suffer and die on their own, or raise them correctly and have no place to store and sell the fish. The first option might be the most reasonable answer for an unexperienced and unprepared betta breeder. But if you do have the money and time, do tons of research as fast as you can, and buy all necessary supplies. Don't try to see if you can skip confusing and complicated steps in the process of raising fry, they're all important. Also, I agree with JKFish. You can use other things besides live food for now, but when you get the time I highly recommend buying or starting a live food hatchery.
P.S. Don't listen to the harsh comments. Some people may get ticked off but you're new to bettas (or betta breeding at the very least), and made a mistake that hopefully wont happen again. Breeding bettas is pretty cool, but it's costly and time consuming.
EDIT: Oh, didn't see that last post. Well R.I.P. fry :(
