Hey, aintlikeitl00ks:
You said you were going to release it once it bred...if it's a male, and if you are willing to spend at least $100 on a breeding-size female, you might get to breed next year. If you buy a hatchling, you'll have to wait 3 years for the female to be breeding size. If the snake is a female, breeding CANNOT take place until it grows AT LEAST 10 inches. This would be AT LEAST a year, and maybe 2 years. And for some reason, you don't seem like the type to spend $100 on a snake. By the time you get to breed them, the snake CANNOT be released. Wild snakes can only be kept for a couple of weeks at most before they should not be returned to the wild.
Here's what you should do if you want a snake:
RELEASE the one you have now, save the money that would have been spent on vet visits and meds,
BUY 2 hatchling corn snakes (less than $20 a piece)
BUY 2 proper setups for the snakes, and the corn snake manual.
RAISE the snakes up to breeding age (2-3 years)
THEN you can breed them.
In all likelyhood, this is the amount of time you would have to spend before you could breed the one you found now.
