WANTED: Female Rats in Central Illinois

I'm looking for a few female rats in my area to start a small breeding operation. I first want to start small with only one group of 1.4-5 just to see if I can handle a larger operation of several breeding groups. I was originally going to just get them from the pet store but they only offer males for some reason, and when I asked for the number of their local supplier all I got was a snarky smart-aleck remark along with a big fat 'no'.(and that was from the owner of the store..needless to say I wont be back there any time soon) So anyways, if anyone has 4-5 breedable female rats available within around 2 hours driving distance of Champaign, IL, please PM me with a price and your location. THANKS!! :)
