I'd see if you could find someone local who breeds out of their home, perhaps as a small business or just for themselves. That's what I do
my current supplier actually just closed but I found someone else using Kijiji (which is an online site similar to Craig's List). I asked a lot of questions about their set up and business and asked for photos.
If that doesn't work, see if you can get in contact with other herpers in your area and share some food! See if anyone else has hatchling and young corns or other snakes that feeds pinky mice and would like to split an order with you; for example, online sellers usually have a minimum quantity to sell. My previous supplier sold in bags of 25.
Try throwing an add out there on a website, or on forums (like this one!), or check out any local reptile clubs or expos coming up to meet people
All the best!
P.S.
I wouldn't even pay $2.45 for an adult mouse, never mind a pinky. What a rip-off!
